The (1) av_image_fill_pointers, (2) vp5_parse_coeff, and (3) vp6_parse_coeff functions in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted VP5 or VP6 stream.

Security readout for executives and security teams

CVE-2011-4353 is an old FFmpeg and Libav flaw where a specially crafted VP5 or VP6 video stream can crash affected media-processing software. The sourced impact is denial of service, not data theft or code execution. Business urgency depends on whether legacy FFmpeg or Libav versions still process untrusted media. Exposure is most likely in legacy systems using FFmpeg 0.5-0.8 or Libav 0.5-0.7, especially upload, transcoding, media inspection, or preview services that parse untrusted video streams. Treat this as a legacy exposure cleanup item unless affected media services are internet-facing or business-critical. It can interrupt service availability, but the provided sources do not support code execution or active exploitation claims. Mitigation focus: Upgrade FFmpeg to 0.5.7, 0.6.4, 0.7.9, 0.8.8, or later as applicable.; Upgrade Libav to 0.5.6, 0.6.4, 0.7.3, or later as applicable.; Use vendor-patched distribution packages where Ubuntu or Mandriva advisories apply..
