    Several vulnerabilities have been discovered in FFmpeg coders, which are used by
    by MPlayer and other applications.
    
    
    CVE-2010-3429
    
      Cesar Bernardini and Felipe Andres Manzano reported an arbitrary offset 
      dereference vulnerability in the libavcodec, in particular in the flic file 
      format parser. A specific flic file may exploit this vulnerability and execute
      arbitrary code. Mplayer is also affected by this problem, as well as other 
      software that use this library.
    
    
    CVE-2010-4704
    
      Greg Maxwell discovered an integer overflow the Vorbis decoder in FFmpeg. A 
      specific ogg file may exploit this vulnerability and execute arbitrary code.
    
    
    CVE-2010-4705
    
      A potential integer overflow has been discovered in the Vorbis decoder in 
      FFmpeg.
    
    
    This upload also fixes an incomplete patch from DSA-2000-1. Michael Gilbert 
    noticed that there was remaining vulnerabilities, which  may cause a denial of 
    service and potentially execution of arbitrary code.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 0.svn20080206-18+lenny3.
    
    We recommend that you upgrade your ffmpeg-debian packages.
