Summary

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)
A flaw was discovered in the FreeType TTF font-file format parser when the TrueType virtual machine Byte Code Interpreter (BCI) is enabled. 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-2008-1808)
The CVE-2008-1808 flaw did not affect the freetype packages as distributed in Red Hat Enterprise Linux 3 and 4, as they are not compiled with TrueType BCI support. A fix for this flaw has been included in this update as usersmay choose to recompile the freetype packages in order to enable TrueType BCI support. Red Hat does not, however, provide support for modified and recompiled packages.
Note: For the FreeType 2 font engine, the CVE-2006-1861, CVE-2007-2754, and CVE-2008-1808 flaws were addressed via RHSA-2006:0500, RHSA-2007:0403, and RHSA-2008:0556 respectively. This update provides corresponding updates for the FreeType 1 font engine, included in the freetype packages distributed in Red Hat Enterprise Linux 3 and 4.
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.
