    It was discovered that ppm2tiff of the tiff tools, a set of utilities for TIFF manipulation and conversion, is not properly checking the return value of an internal function used in order to detect integer overflows. As a consequence, ppm2tiff suffers of a heap-based buffer overflow.

    Package        : tiff
    Vulnerability  : heap-based buffer overflow
    Problem type   : local (remote)
    Debian-specific: no
    CVE ID         : CVE-2012-4564
    
    It was discovered that ppm2tiff of the tiff tools, a set of utilities
    for TIFF manipulation and conversion, is not properly checking the return
    value of an internal function used in order to detect integer overflows.
    As a consequence, ppm2tiff suffers of a heap-based buffer overflow.
    This allows attacker to potentially execute arbitrary code via a crafted
    ppm image, especially in scenarios in which images are automatically
    processed.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 3.9.4-5+squeeze7.
    
    For the testing distribution (wheezy), this problem will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.0.2-5.
    
    We recommend that you upgrade your tiff packages.
