RHSA-2012:1590 - Moderate: libtiff security update

Synopsis

Moderate: libtiff security update

Type/Severity

Security Advisory Moderate

Topic

Updated libtiff packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

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. (CVE-2012-4447)

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. (CVE-2012-5581)

A heap-based buffer overflow flaw was found in the tiff2pdf tool. An attacker could use this flaw to create a specially-crafted TIFF file that would cause tiff2pdf to crash or, possibly, execute arbitrary code. (CVE-2012-3401)

A missing return value check flaw, leading to a heap-based buffer overflow, was found in the ppm2tiff tool. An attacker could use this flaw to create a specially-crafted PPM (Portable Pixel Map) file that would cause ppm2tiff to crash or, possibly, execute arbitrary code. (CVE-2012-4564)

The CVE-2012-5581, CVE-2012-3401, and CVE-2012-4564 issues were discovered by Huzaifa Sidhpurwala of the Red Hat Security Response Team.

All libtiff users should upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications linked against libtiff must be restarted for this update to take effect.
