Doc Text:
A flaw was found in SDL_mixer. A stack-based buffer overflow vulnerability exists in the WAV audio decoder when processing audio streams compressed with A-law or mu-law formats. By enticing a user or application to process a specially crafted WAV file, an attacker could overwrite stack memory, potentially leading to arbitrary code execution or an application crash resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-05 22:10:10 UTC 
SDL_mixer 3.1.2 through 3.2.4 contains a stack-based buffer overflow vulnerability in FetchXLaw() of src/decoder_wav.c when decoding A-law or mu-law WAV files. Attackers can supply a crafted WAV file whose doubly-offset float expansion overwrites about 1 KB of adjacent stack memory, causing crashes or potentially code execution.
