High level conclusions

Fuzzer test/fuzz/fuzz_deparse.c is blocked:

The runtime code coverage of test/fuzz/fuzz_deparse.c covers 17.32% of its statically reachable code. This means there is some place that blocks the fuzzer to continue exploring more code at run time.

Fuzzers reach 10.59% of cyclomatic complexity.

Fuzzers reach 2.577% of all functions.

Reachability and coverage overview

Functions statically reachable by fuzzers

910 / 35310

Cyclomatic complexity statically reachable by fuzzers

3572 / 33723

Runtime code coverage of functions

1680 / 35310

Warning: The number of runtime covered functions are larger than the number of reachable functions. This means that Fuzz Introspector found there are more functions covered at runtime than what is considered reachable based on the static analysis. This is a limitation in the analysis as anything covered at runtime is by definition reachable by the fuzzers.
This is likely due to a limitation in the static analysis. In this case, the count of functions covered at runtime is the true value, which means this is what should be considered "achieved" by the fuzzer.

Use the project functions table below to query all functions that were not covered at runtime.

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 .

Func name	Functions filename	Args	Function call depth	Reached by Fuzzers	Runtime reached by Fuzzers	Combined reached by Fuzzers	Fuzzers runtime hit	Func lines hit %	I Count	BB Count	Cyclomatic complexity	Functions reached	Reached by functions	Accumulated cyclomatic complexity	Undiscovered complexity

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.

Runtime coverage analysis

Covered functions

394

Functions that are reachable but not covered

83

Reachable functions

129

Percentage of reachable functions covered

35.66%

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.

Warning: The number of covered functions are larger than the number of reachable functions. This means that there are more functions covered at runtime than are extracted using static analysis. This is likely a result of the static analysis component failing to extract the right call graph or the coverage runtime being compiled with sanitizers in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

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.

Func name	Functions filename	Arg count	Args	Function depth	hitcount	instr count	bb count	cyclomatic complexity	Reachable functions	Incoming references	total cyclomatic complexity	Unreached complexity
pg_query::Node::_InternalSerialize	/src/libpg_query/protobuf/pg_query.pb.cc	2	['::uint8_t*', '::google::protobuf::io::EpsCopyOutputStream*']	29	0	1082	271	271	1470	0	4525	1704

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

Functions statically reachable by fuzzers

1250 / 35310

Cyclomatic complexity statically reachable by fuzzers

5276 / 33723

All functions overview

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

Func name	Functions filename	Args	Function call depth	Reached by Fuzzers	Runtime reached by Fuzzers	Combined reached by Fuzzers	Fuzzers runtime hit	Func lines hit %	I Count	BB Count	Cyclomatic complexity	Functions reached	Reached by functions	Accumulated cyclomatic complexity	Undiscovered complexity

This sections provides heuristics that can be used as input to a fuzz engine when running a given fuzz target. The current focus is on providing input that is usable by libFuzzer.

New fuzzers

The below fuzzers are templates and suggestions for how to target the set of optimal functions above

pg_query.pb.cc

Target file: /src/libpg_query/protobuf/pg_query.pb.cc
Target functions: pg_query::Node::_InternalSerialize

#include "ada_fuzz_header.h"

int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
  af_safe_gb_init(data, size);

  /* target pg_query::Node::_InternalSerialize */
  UNKNOWN_TYPE unknown_0;
  UNKNOWN_TYPE unknown_1;
  pg_query::Node::_InternalSerialize(unknown_0, unknown_1);

  af_safe_gb_cleanup();
}

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

This section shows a list of 3rd party function calls and their relative coverage information. By static analysis of the target project code, all of the 3rd party function call and their caller information, including the source file and line number that initiate the call are captured. The caller source code file and line number are shown in column 2 while column 1 is the function name of the 3rd party function call. Each occurrent of the 3rd party function call will occuply a separate row. Column 3 of each row indicate if the 3rd party call in the source file line is unreachable. Column 4 lists all fuzzers that have covered that particular system call in that specific location (source file and line)during their dynamic fuzzing.

Function in each files in report

Target sink	Callsite location	Reached by fuzzer	Covered by Fuzzers

This section contains multiple tables, each table contains a list of sink functions/methods found in the project for one of the CWE supported by the sink analyser, together with information like which fuzzers statically reach the sink functions/methods and possible call path to that sink functions/methods if it is not statically reached by any fuzzers. Column 1 is the function/method name of the sink functions/methods found in the project. Column 2 lists all fuzzers (or no fuzzers at all) that have covered that particular function method statically. Column 3 shows a list of possible call paths to reach the specific function/method call if none of the fuzzers cover the target function/method calls. Lastly, column 4 shows possible fuzzer blockers that prevent an existing fuzzer from reaching the target sink functions/methods dynamically.
