Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Runtime coverage analysis

Covered functions

47

Functions that are reachable but not covered

2521

Reachable functions

2565

Percentage of reachable functions covered

1.72%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: matrixsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3969	46.3%
gold	[1:9]	4112	48.0%
yellow	[10:29]	16	0.18%
greenyellow	[30:49]	14	0.16%
lawngreen	50+	449	5.24%
All colors	8560	100

Runtime coverage analysis

Covered functions

1338

Functions that are reachable but not covered

1880

Reachable functions

2565

Percentage of reachable functions covered

26.71%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: heifsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3964	46.3%
gold	[1:9]	4106	47.9%
yellow	[10:29]	14	0.16%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	474	5.53%

Runtime coverage analysis

Covered functions

1389

Functions that are reachable but not covered

1872

Reachable functions

2565

Percentage of reachable functions covered

27.02%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: generic_buffer_with_args_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3814	44.4%
gold	[1:9]	4149	48.4%
yellow	[10:29]	41	0.47%
greenyellow	[30:49]	3	0.03%
lawngreen	50+	564	6.58%
All colors	8571	100

Runtime coverage analysis

Covered functions

1447

Functions that are reachable but not covered

1847

Reachable functions

2569

Percentage of reachable functions covered

28.1%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: mosaic_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3978	46.6%
gold	[1:9]	4106	48.1%
yellow	[10:29]	24	0.28%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	422	4.94%
All colors	8532	100

Runtime coverage analysis

Covered functions

1287

Functions that are reachable but not covered

1890

Reachable functions

2564

Percentage of reachable functions covered

26.29%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: webpsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3958	46.2%
gold	[1:9]	4094	47.8%
yellow	[10:29]	31	0.36%
greenyellow	[30:49]	4	0.04%
lawngreen	50+	473	5.52%
All colors	8560	100

Runtime coverage analysis

Covered functions

1399

Functions that are reachable but not covered

1869

Reachable functions

2565

Percentage of reachable functions covered

27.13%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: csvsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3980	46.4%
gold	[1:9]	4097	47.8%
yellow	[10:29]	32	0.37%
greenyellow	[30:49]	5	0.05%
lawngreen	50+	446	5.21%
All colors	8560	100

Runtime coverage analysis

Covered functions

1326

Functions that are reachable but not covered

1884

Reachable functions

2565

Percentage of reachable functions covered

26.55%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: radsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3958	46.2%
gold	[1:9]	4097	47.8%
yellow	[10:29]	32	0.37%
greenyellow	[30:49]	3	0.03%
lawngreen	50+	470	5.49%
All colors	8560	100

Runtime coverage analysis

Covered functions

1392

Functions that are reachable but not covered

1870

Reachable functions

2565

Percentage of reachable functions covered

27.1%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: pngsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3958	46.2%
gold	[1:9]	4101	47.9%
yellow	[10:29]	25	0.29%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	474	5.53%
All colors	8560	100

Runtime coverage analysis

Covered functions

1391

Functions that are reachable but not covered

1871

Reachable functions

2565

Percentage of reachable functions covered

27.06%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: tiffsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3982	46.5%
gold	[1:9]	4113	48.0%
yellow	[10:29]	13	0.15%
greenyellow	[30:49]	5	0.05%
lawngreen	50+	447	5.22%
All colors	8560	100

Runtime coverage analysis

Covered functions

1332

Functions that are reachable but not covered

1888

Reachable functions

2565

Percentage of reachable functions covered

26.39%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: sharpen_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3954	46.3%
gold	[1:9]	4113	48.2%
yellow	[10:29]	14	0.16%
greenyellow	[30:49]	3	0.03%
lawngreen	50+	442	5.18%
All colors	8526	100

Runtime coverage analysis

Covered functions

1445

Functions that are reachable but not covered

1861

Reachable functions

2562

Percentage of reachable functions covered

27.36%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: thumbnail_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3958	46.4%
gold	[1:9]	4104	48.1%
yellow	[10:29]	14	0.16%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	448	5.25%
All colors	8526	100

Runtime coverage analysis

Covered functions

1501

Functions that are reachable but not covered

1857

Reachable functions

2562

Percentage of reachable functions covered

27.52%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: gifsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3958	46.2%
gold	[1:9]	4101	47.9%
yellow	[10:29]	27	0.31%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	472	5.51%

Runtime coverage analysis

Covered functions

1416

Functions that are reachable but not covered

1867

Reachable functions

2565

Percentage of reachable functions covered

27.21%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: smartcrop_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3948	46.3%
gold	[1:9]	4112	48.2%
yellow	[10:29]	14	0.16%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	450	5.27%
All colors	8526	100

Runtime coverage analysis

Covered functions

1505

Functions that are reachable but not covered

1849

Reachable functions

2562

Percentage of reachable functions covered

27.83%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: rawsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3970	46.3%
gold	[1:9]	4125	48.1%
yellow	[10:29]	17	0.19%
greenyellow	[30:49]	2	0.02%
lawngreen	50+	446	5.21%
All colors	8560	100

Runtime coverage analysis

Covered functions

1298

Functions that are reachable but not covered

1885

Reachable functions

2565

Percentage of reachable functions covered

26.51%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: ppmsave_buffer_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3959	46.2%
gold	[1:9]	4095	47.8%
yellow	[10:29]	31	0.36%
greenyellow	[30:49]	3	0.03%
lawngreen	50+	472	5.51%
All colors	8560	100

Runtime coverage analysis

Covered functions

1390

Functions that are reachable but not covered

1870

Reachable functions

2565

Percentage of reachable functions covered

27.1%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.

Fuzzer: jpegsave_file_fuzzer

Call tree

The calltree shows the control flow of the fuzzer. This is overlaid with coverage information to display how much of the potential code a fuzzer can reach is in fact covered at runtime. In the following there is a link to a detailed calltree visualisation as well as a bitmap showing a high-level view of the calltree. For further information about these topics please see the glossary for full calltree and calltree overview

Call tree overview bitmap:

The distribution of callsites in terms of coloring is

Color	Runtime hitcount	Callsite count	Percentage
red	0	3893	45.6%
gold	[1:9]	4112	48.1%
yellow	[10:29]	5	0.05%
greenyellow	[30:49]	6	0.07%
lawngreen	50+	517	6.05%
All colors	8533	100

Runtime coverage analysis

Covered functions

1513

Functions that are reachable but not covered

1842

Reachable functions

2567

Percentage of reachable functions covered

28.24%

NB: The sum of covered functions and functions that are reachable but not covered need not be equal to Reachable functions . This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation of our static analysis capabilities.
