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)

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.

File List

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.

Robert Swiecki discovered several vulnerabilities in the FreeType font library, which could lead to the execution of arbitrary code if a malformed font file is processed.

Also, several buffer overflows were found in the included demo programs.

Robert Swiecki discovered that FreeType did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could execute arbitrary code with user privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in freetype2 :

Multiple integer underflows/overflows and heap buffer overflows was discovered and fixed (CVE-2010-2497, CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519).

A heap buffer overflow was discovered in the bytecode support. The bytecode support is NOT enabled per default in Mandriva due to previous patent claims, but packages by PLF is affected (CVE-2010-2520).

Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct these issues.

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