RHEL 4 : freetype (RHSA-2009:0329)

high Nessus Plugin ID 38870

Synopsis

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

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:0329 advisory.

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 users may 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL freetype package based on the guidance in RHSA-2009:0329.
