RHSA-2011:1161 - Moderate: freetype security update

Synopsis

Moderate: freetype security update

Type/Severity

Security Advisory Moderate

Topic

Updated freetype packages that fix one security issue are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having moderate 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

FreeType is a free, high-quality, portable font engine that can open and manage font files. It also loads, hints, and renders individual glyphs efficiently. These packages provide both the FreeType 1 and FreeType 2 font engines.

A buffer overflow flaw was found in the way the FreeType library handled malformed font files compressed using UNIX compress. If a user loaded a specially-crafted compressed font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-2895)

Note: This issue only affects the FreeType 2 font engine.

Users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The X server must be restarted (log out, then log back in) for this update to take effect.
