Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated freetype packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

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

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. The freetype packages for Red Hat Enterprise Linux 4 provide both the FreeType 1 and FreeType 2 font engines. The freetype packages for Red Hat Enterprise Linux 5 provide only the FreeType 2 font engine.

It was discovered that the FreeType font rendering engine improperly validated certain position values when processing input streams. If a user loaded a specially crafted font file with an application linked against FreeType, and the relevant font glyphs were subsequently rendered with the X FreeType library (libXft), it could trigger a heap-based buffer overflow in the libXft library, causing the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-3311)

A stack-based buffer overflow flaw was found in the way the FreeType font rendering engine processed some PostScript Type 1 fonts. If a user loaded a specially 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-2010-2808)

An array index error was found in the way the FreeType font rendering engine processed certain PostScript Type 42 font files. If a user loaded a specially 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-2010-2806)

A stack overflow flaw was found in the way the FreeType font rendering engine processed PostScript Type 1 font files that contain nested Standard Encoding Accented Character (seac) calls. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash. (CVE-2010-3054)

Note: All of the issues in this erratum only affect the FreeType 2 font engine.

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.

Solution

Update the affected packages.
