RHSA-2006:0500 - freetype security update

Synopsis

freetype security update

Type/Severity

Security Advisory Moderate

Topic

Updated freetype packages that fix several security flaws are now available for Red Hat Enterprise Linux.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Description

FreeType is a free, high-quality, and portable font engine.

Chris Evans discovered several integer underflow and overflow flaws in the FreeType font engine. If a user loads a carefully crafted font file with a program linked against FreeType, it could cause the application to crash or execute arbitrary code as the user. While it is uncommon for a user to explicitly load a font file, there are several application file formats which contain embedded fonts that are parsed by FreeType. (CVE-2006-0747, CVE-2006-1861, CVE-2006-3467)

A NULL pointer dereference flaw was found in the FreeType font engine. An application linked against FreeType can crash upon loading a malformed font file. (CVE-2006-2661)

Users of FreeType should upgrade to these updated packages, which contain backported patches to correct these issues.
