Gentoo Linux Security Advisory 201402-21 - Multiple vulnerabilities have been found in libTIFF, allowing remote attackers to execute arbitrary code or cause Denial of Service. Versions less than 4.0.3-r6 are affected.
707bad1294ac3b0a266eaeb2ec4cb55aa7008c0ab780cd9c1f258db6072baa3aSlackware Security Advisory - New libtiff packages are available for Slackware 12.1, 12.2, 13.0, 13.1, 13.37, 14.0, and -current to fix security issues.

8efbfdf677fa9982c5f47aeec194dfc0fddb0fe6852beca1661e63d8b3687b4bMandriva Linux Security Advisory 2013-046 - libtiff did not properly convert between signed and unsigned integer values, leading to a buffer overflow. An attacker could use this flaw to create a specially-crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the tiff2pdf tool. An attacker could use these flaws to create a specially-crafted TIFF file that would cause tiff2pdf to crash or, possibly, execute arbitrary code. Huzaifa Sidhpurwala discovered that the tiff2pdf utility incorrectly handled certain malformed TIFF images. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. It was discovered that a buffer overflow in libtiff's parsing of files using PixarLog compression could lead to the execution of arbitrary code. ppm2tiff does not check the return value of the TIFFScanlineSize function, which allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted PPM image that triggers an integer overflow, a zero-memory allocation, and a heap-based buffer overflow. It was discovered that LibTIFF incorrectly handled certain malformed images using the DOTRANGE tag. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.

A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF images using the Pixar Log Format encoding. An attacker could create a specially-crafted TIFF file that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with the privileges of the user running the application. A stack-based buffer overflow flaw was found in the way libtiff handled DOTRANGE tags. An attacker could use this flaw to create a specially-crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code.

The updated packages have been patched to correct these issues.

If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. Huzaifa S. Sidhpurwala discovered that the ppm2tiff tool incorrectly handled certain malformed PPM images. If a user or automated system were tricked into opening a specially crafted PPM image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. Various other issues were also addressed.
