SecurityTracker URL:  http://securitytracker.com/id/1020338
CVE Reference:   CVE-2008-1807   (Links to External Site)
Date:  Jun 20 2008
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.3.5 and prior versions
Description:   A vulnerability was reported in FreeType2. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted Printer Font Binary (PFB) format font file that, when loaded by the target user or application, will trigger a memory corruption error and execute arbitrary code on the target system. The code will run with the privileges of the target user or application.

A specially crafted 'number of axes' in a PFB file can trigger code execution.

The vendor was notified on June 3, 2008.

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)
font-file format parser. 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, did not affect the freetype packages as shipped
in Red Hat Enterprise Linux 3, 4, and 5, as they are 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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

450768 - CVE-2008-1806 FreeType PFB integer overflow
450773 - CVE-2008-1807 FreeType invalid free() flaw
450774 - CVE-2008-1808 FreeType off-by-one flaws
