Synopsis

Important: libtiff security update

Type / Sévérité

Security Advisory: Important

Sujet

Updated libtiff packages that fix one security issue are now available for
Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link 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 Internet Fax image files, compressed with the CCITT Group 4
compression algorithm. 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-2011-0192)

Red Hat would like to thank Apple Product Security for reporting this
issue.

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

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
