RHEL 3 / 4 / 5 : freetype (RHSA-2010:0607)

High Nessus Plugin ID 48258


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


Updated freetype packages that fix two security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

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.

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 3 and 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.

Two stack overflow flaws were found in the way the FreeType font engine processed certain Compact Font Format (CFF) character strings (opcodes). 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-2010-1797)

Red Hat would like to thank Braden Thomas of the Apple Product Security team for reporting these issues.

Note: CVE-2010-1797 only affects the FreeType 2 font engine.

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


Update the affected packages.
