    Package        : tiff
    Vulnerability  : heap overflows
    Problem-Type   : remote

    CVE ID         : CAN-2004-0803 CAN-2004-0804 CAN-2004-0886
    Several problems have been discovered in libtiff, the Tag Image File
    Format library for processing TIFF graphics files.  An attacker could
    prepare a specially crafted TIFF graphic that would cause the client
    to execute arbitrary code or crash.  The Common Vulnerabilities and
    Exposures Project has identified the following problems:
        Chris Evans discovered several problems in the RLE (run length
        encoding) decoders that could lead to arbitrary code execution.
        Matthias Clasen discovered a division by zero through an integer
        Dmitry V. Levin discovered several integer overflows that caused
        malloc issues which can result to either plain crash or memory
    For the stable distribution (woody) these problems have been fixed in
    version 3.5.5-6woody1.
    For the unstable distribution (sid) these problems have been fixed in
    version 3.6.1-2.
    We recommend that you upgrade your libtiff package.
