    Debian Bug     : 678140
    
    Several vulnerabilities were discovered in Tiff, a library set and tools 
    to support the Tag Image File Format (TIFF), allowing denial of service and
    potential privilege escalation.
    
    These vulnerabilities can be exploited via a specially crafted TIFF image.
    
    CVE-2012-2113
      The tiff2pdf utility has an integer overflow error when parsing images.
    
    CVE-2012-3401
      Huzaifa Sidhpurwala discovered heap-based buffer overflow in the 
      t2p_read_tiff_init() function.
    
    CVE-2010-2482
      An invalid td_stripbytecount field is not properly handle and can trigger a
      NULL pointer dereference.
    
    CVE-2010-2595
      An array index error, related to "downsampled OJPEG input." in the
      TIFFYCbCrtoRGB function causes an unexpected crash.
    
    CVE-2010-2597
      Also related to "downsampled OJPEG input", the TIFFVStripSize function crash
      unexpectly.
    
    CVE-2010-2630
      The TIFFReadDirectory function does not properly validate the data types of 
      codec-specific tags that have an out-of-order position in a TIFF file.
    
    CVE-2010-4665
      The tiffdump utility has an integer overflow in the ReadDirectory function.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 3.9.4-5+squeeze5.
    
    For the testing distribution (wheezy), these problems have been fixed in
    version 4.0.2-2.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 4.0.2-2.
    
    We recommend that you upgrade your tiff packages.
