Project functions overview

The following table shows data about each function in the project. The functions included in this table correspond to all functions that exist in the executables of the fuzzers. As such, there may be functions that are from third-party libraries.

For further technical details on the meaning of columns in the below table, please see the Glossary .

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
614
Functions that are reachable but not covered
1370
Reachable functions
1624
Percentage of reachable functions covered
15.64%
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.

Optimal target analysis

Remaining optimal interesting functions

The following table shows a list of functions that are optimal targets. Optimal targets are identified by finding the functions that in combination, yield a high code coverage.

Implementing fuzzers that target the above functions will improve reachability such that it becomes:

Functions statically reachable by fuzzers
46.98%
2349/5000
Cyclomatic complexity statically reachable by fuzzers
53.8%
13807 / 25664

All functions overview

If you implement fuzzers for these functions, the status of all functions in the project will be:

Files and Directories in report

This section shows which files and directories are considered in this report. The main reason for showing this is fuzz introspector may include more code in the reasoning than is desired. This section helps identify if too many files/directories are included, e.g. third party code, which may be irrelevant for the threat model. In the event too much is included, fuzz introspector supports a configuration file that can exclude data from the report. See the following link for more information on how to create a config file: link

Function call coverage

This section shows a chosen list of functions / methods calls and their relative coverage information. By static analysis of the target project code, all of these function call and their caller information, including the source file or class and line number that initiate the call are captured. The caller source code file or class and the line number are shown in column 2 while column 1 is the function name of that selected functions or methods call. Each occurrent of the target function call will occuply a separate row. Column 3 of each row indicate if the target function calls is statically unreachable.Column 4 lists all fuzzers (or no fuzzers at all) that have covered that particular system call in dynamic fuzzing. Those functions with low to no reachability and dynamic hit count indicate missed fuzzing logic to fuzz and track for possible code injection sinks.
