    Debian Bug     : 611495
    
    
    Several vulnerabilities have been discovered in ffmpeg, a multimedia player,
    server and encoder.
    The Common Vulnerabilities and Exposures project identifies the following
    problems:
    
    
    CVE-2010-3908
    
       FFmpeg before 0.5.4, allows remote attackers to cause a denial of service
       (memory corruption and application crash) or possibly execute arbitrary code
       via a malformed WMV file.
    
    
    CVE-2010-4704
    
       libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg allows remote
       attackers to cause a denial of service (application crash) via a crafted
       .ogg file, related to the vorbis_floor0_decode function.
    
    
    CVE-2011-0480
    
       Multiple buffer overflows in vorbis_dec.c in the Vorbis decoder in FFmpeg
       allow remote attackers to cause a denial of service (memory corruption and
       application crash) or possibly have unspecified other impact via a crafted
       WebM file, related to buffers for the channel floor and the channel residue.
    
    
    CVE-2011-0722
    
       FFmpeg allows remote attackers to cause a denial of service (heap memory
       corruption and application crash) or possibly execute arbitrary code via a
       malformed RealMedia file.
    
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4:0.5.4-1.
    
    Security support for ffmpeg has been discontinued for the oldstable
    distribution (lenny).
    The current version in oldstable is not supported by upstream anymore
    and is affected by several security issues. Backporting fixes for these
    and any future issues has become unfeasible and therefore we need to
    drop our security support for the version in oldstable.
    
    
    We recommend that you upgrade your ffmpeg packages.
