Multiple unspecified vulnerabilities in FFmpeg 0.4.x through 0.6.x, as used in MPlayer 1.0 and other products, in Mandriva Linux 2009.0, 2010.0, and 2010.1; Corporate Server 4.0 (aka CS4.0); and Mandriva Enterprise Server 5 (aka MES5) have unknown impact and attack vectors, related to issues "originally discovered by Google Chrome developers."
FFmpeg 0.5.x, as used in MPlayer and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed VC-1 file.
libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg 0.6.1 and earlier allows remote attackers to cause a denial of service (application crash) via a crafted .ogg file, related to the vorbis_floor0_decode function. NOTE: this might overlap CVE-2011-0480.
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."
Integer signedness error in the fourxm_read_header function in libavformat/4xm.c in FFmpeg before revision 16846 allows remote attackers to execute arbitrary code via a malformed 4X movie file with a large current_track value, which triggers a NULL pointer dereference.
