Remediated Vulnerabilities

CWE-122: Heap-based Buffer Overflow

Severity: High
Location:

• src/fsearch_database.c
• src/test_build/fsearch_database.c

Details:
The application parses a custom binary database format and reads data directly into memory blocks. Manual memcpy operations were previously used without sufficient bounds validation, posing a risk of buffer overflows if the parsed data lengths exceeded the allocated buffers or the end of the memory block.

Remediation:

• A safe macro, DB_READ_MEM, was introduced to replace all unchecked memcpy operations.
• DB_READ_MEM enforces strict bounds checking against both the available source memory (end - src) and the destination buffer capacity (dest_size).
• The macro safely halts processing (src = NULL) if boundaries are violated, preventing unchecked pointer arithmetic and memory corruption.
• This safe logic was successfully mirrored to the test_build counterparts to ensure uniformity and secure test builds.

Conclusion

With the implementation of the bounds-checked macro, the ModFS database loading routines are significantly hardened against buffer overflow attacks. No further action is required for these findings, and the latest Snyk scan confirms zero vulnerabilities.
