Synopsis: Important: freetype security update
Advisory ID: RHSA-2008:0558-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0558.html

=====================================================================
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Description:
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),
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.
