Target oracle

This page shows functions across the entire OSS-Fuzz database that are determined to be likely interesting targets. This suggestion comes from various heuristics that often encapsulate functions that are likely good to fuzz or are, perhaps, easy to fuzz. For each suggestion a justification is included as to why this target is interesting, by way of referencing a given heuristic.

Heuristics

Heuristic 1

This is the heuristic highlights functions that has all of the following attributes:

- Has "parse" in its function name.
- Has zero percentage code coverage.
- Has accumulated cyclomatic complexity larger than 200.
- Is in a project written in C or C++.

Heuristic 2

This is the heuristic highlights functions that has all of the following attributes:

- Has two arguments.
- First argument has type "char *".
- Second argument has type "int".
- Has accumulated cyclomatic complexity larger than 150
