FFmpeg version n6.1 was discovered to contain an improper validation of array index vulnerability in libavcodec/cbsh266syntaxtemplate.c. This vulnerability allows attackers to cause undefined behavior within the application.
FFmpeg n7.0 is affected by a Double Free via the rkmppretrieveframe function within libavcodec/rkmppdec.c.
The 'vp3decodeframe' function in FFmpeg 1.1.4 moves threads check out of header packet type check.
FFmpeg before commit cced03dd667a5df6df8fd40d8de0bff477ee02e8 contains multiple out of array access vulnerabilities in the mms protocol that can result in attackers accessing out of bound data. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in cced03dd667a5df6df8fd40d8de0bff477ee02e8 and later.

Original Despcription
FFmpeg 0.7.0 and below was discovered to contain a code injection vulnerability in the component net.bramp.ffmpeg.FFmpeg.<constructor>. This vulnerability is exploited via passing an unchecked argument.
The VC-1 decoding functionality in FFmpeg before 0.5.4, as used in MPlayer and other products, does not properly restrict read operations, which allows remote attackers to have an unspecified impact via a crafted VC-1 file, a related issue to CVE-2011-0723.
