FFmpeg through 9.0.2 contains an integer overflow vulnerability in hap_parse_frame_header() in libavcodec/hapdec.c that allows attackers to trigger a heap buffer overflow on 32-bit builds. Attackers can craft Hap video frames with Snappy length prefixes that wrap tex_size, causing decompress_chunks_thread() to write outside tex_buf and crash the application or potentially execute code.

Ein Angreifer kann mehrere Schwachstellen in ffmpeg ausnutzen, um einen Denial-of-Service-Zustand auszulösen, Daten zu manipulieren oder offenzulegen, Sicherheitsmaßnahmen zu umgehen, Speicherbeschädigungen zu verursachen und möglicherweise beliebigen Code auszuführen.
