"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."
