RHSA-2009:1062 - Important: freetype security update

Synopsis

Important: freetype security update

Type/Severity

Security Advisory Important

Topic

Updated freetype packages that fix various security issues are now available for Red Hat Enterprise Linux 2.1.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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.

Tavis Ormandy of the Google Security Team discovered several integer overflow flaws in the FreeType 2 font engine. If a user loaded a carefully-crafted font file with an application linked against FreeType 2, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2009-0946)

Chris Evans discovered multiple integer overflow flaws in the FreeType font engine. If a user loaded a carefully-crafted 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-2006-1861)

An integer overflow flaw was found in the way the FreeType font engine processed TrueType® Font (TTF) files. If a user loaded a carefully-crafted 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-2007-2754)

Note: For the FreeType 2 font engine, the CVE-2006-1861 and CVE-2007-2754 flaws were addressed via RHSA-2006:0500 and RHSA-2007:0403 respectively. This update provides corresponding updates for the FreeType 1 font engine, included in the freetype packages distributed in Red Hat Enterprise Linux 2.1.

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