CVE-2024-50613Public exploitNetwork attack vector

Application crash via crafted RIFF-to-MP3 conversion

Published Oct 27, 2024 · Updated Oct 30, 2024

Reachable assertion in MP3 encoding in libsndfile 1.2.2 and earlier allows context-dependent attackers to crash an application via a crafted RIFF file. The mpeg_l3_encode.c encoding path passes attacker-shaped audio into libmp3lame, where calc_energy's el >= 0 assertion fails and aborts the process. MP3 encoding must be enabled through LAME, and a consuming application must convert attacker-controlled audio; no data access or code execution is reported.
