Description

Updated freetype packages that fix various security issues are now available for Red Hat Enterprise Linux 2.1.

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

[Updated 25th June 2008] The original packages distributed with this errata had a bug which prevented freetype library from loading certain font files correctly. We have updated the packages to correct this bug.

FreeType is a free, high-quality, portable font engine that can open and manage font files, as well as efficiently load, hint and render individual glyphs.

Multiple flaws were discovered in FreeType's Printer Font Binary (PFB) and TrueType Font (TTF) font-file format parsers. If a user loaded a carefully crafted font-file with a program linked against FreeType, it could cause the application to crash, or possibly execute arbitrary code. (CVE-2008-1806, CVE-2008-1807, CVE-2008-1808)

Note: the flaw in FreeType's TrueType Font (TTF) font-file format parser, covered by CVE-2008-1808, only affected the FreeType 1 library (libttf), which shipped in the freetype packages in Red Hat Enterprise Linux 2.1. The FreeType 2 library (libfreetype) is not affected, as it is not compiled with TTF Byte Code Interpreter (BCI) support.

Users of freetype should upgrade to these updated packages, which contain backported patches to resolve these issues.
