FFmpeg ws_snd_decode_frame buffer overflow
|ffmpeg-wssnddecodeframe-bo (78936)||High Risk|
FFmpeg is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the ws_snd_decode_frame function. By persuading a victim to open a specially-crafted media file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Upgrade to the latest version of FFmpeg (0.9.1 or later), available from the FFmpeg Web site. See References.
