Synopsis
The remote Red Hat host is missing one or more security updates.
Description
Updated freetype packages that fix various 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.
An invalid memory management flaw was found in the way the FreeType font engine processed font 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-2010-2498)
An integer overflow flaw was found in the way the FreeType font engine processed font 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-2010-2500)
Several buffer overflow flaws were found in the way the FreeType font engine processed font 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-2010-2499, CVE-2010-2519)
Several buffer overflow flaws were found in the FreeType demo applications. If a user loaded a carefully-crafted font file with a demo application, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-2527, CVE-2010-2541)
Red Hat would like to thank Robert Swiecki of the Google Security Team for the discovery of the CVE-2010-2498, CVE-2010-2500, CVE-2010-2499, CVE-2010-2519, and CVE-2010-2527 issues.
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.
