Several vulnerabilities have been discovered in the Tag Image File
Format (TIFF) library and its associated tools.

CVE-2017-11335

    A heap based buffer overflow via a PlanarConfig=Contig image, which
    causes an out-of-bounds write (related to the ZIPDecode function). A
    crafted input may lead to a remote denial of service attack or an
    arbitrary code execution attack.

CVE-2017-12944

    A mishandling of memory allocation for short files allows attackers
    to cause a denial of service (allocation failure and application
    crash) during a tiff2pdf invocation.

CVE-2017-13726

    A reachable assertion abort allows a crafted input to lead to a
    remote denial of service attack.

CVE-2017-13727

    A reachable assertion abort allows a crafted input to lead to a
    remote denial of service attack.

For Debian 7 "Wheezy", these problems have been fixed in version
4.0.2-6+deb7u16.

We recommend that you upgrade your tiff packages.
