AI risk analysis
- Summary
- The flaw involves an integer overflow in W64 CUE chunk metadata parsing within dr_libs dr_wav.h, leading to potential buffer overflows and data corruption.
- Exploitability
- Exploitation requires access to process memory and specific conditions on the build environment; it is moderately difficult given these constraints.
- Blast radius
- If exploited, this could lead to severe system instability or remote code execution, depending on the application's context.
- Prioritized remediation
- Update to a patched version of dr_libs or apply a custom fix that ensures proper handling of chunk sizes.

NVD description
dr_libs dr_wav.h (all versions through current master) contains an integer overflow in W64 CUE chunk metadata parsing. In drwav__metadata_process_chunk, a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to size_t before dividing by DRWAV_CUE_POINT_BYTES; on 32-bit builds this truncation causes the pre-allocated extra metadata capacity to be computed incorrectly.
