flicvideo.c in libavcodec 0.6 and earlier in FFmpeg, as used in MPlayer and other products, allows remote attackers to execute arbitrary code via a crafted flic file, related to an "arbitrary offset dereference vulnerability."

FFmpeg 0.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted MOV container with improperly ordered tags that cause (1) mov.c and (2) utils.c to use inconsistent codec types and identifiers, leading to processing of a video-structure pointer by the mp3 decoder, and a stack-based buffer overflow.

FFmpeg 0.5 allows remote attackers to cause a denial of service (hang) via a crafted file that triggers an infinite loop.

A flaw was found in FFmpeg. This vulnerability allows unexpected additional CPU load and storage consumption, potentially leading to degraded performance or denial of service via the demuxing of arbitrary data as XBIN-formatted data without proper format validation.

A flaw was found in FFmpeg's TTY Demuxer. This vulnerability allows possible data exfiltration via improper parsing of non-TTY-compliant input files in HLS playlists.

A flaw was found in FFmpeg's DASH playlist support. This vulnerability allows arbitrary HTTP GET requests to be made on behalf of the machine running FFmpeg via a crafted DASH playlist containing malicious URLs.

Buffer Overflow vulnerability in Ffmpeg v.N113007-g8d24a28d06 allows a local attacker to execute arbitrary code via the libavfilter/avf_showwaves.c:722:24 in showwaves_filter_frame

The Matroska format decoder in FFmpeg before 0.8.3 does not properly allocate memory, which allows remote attackers to execute arbitrary code via a crafted file.
