Overview

CVE-2021-44269 affects WavPack version 5.4.0, an open audio compression format software. The vulnerability was discovered in the WavpackPackSamples function within src/pack_utils.c, where an out-of-bounds read vulnerability exists when processing WAV files (NVD, GitHub Issue).

Technical details

The vulnerability occurs in the WavpackPackSamples function in src/pack_utils.c. The issue arises when the variable 'cnt' becomes too large, causing the pointer 'sptr' to read beyond heap boundaries. This happens specifically in the code block between lines 628-636 when processing mono flag operations (GitHub Issue).
