Red Hat Security Advisory

 

Synopsis: Important: freetype security update

Advisory ID: RHSA-2010:0736-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0736.html

Issue date: 2010-10-04

CVE Names: CVE-2010-2806 CVE-2010-3054 CVE-2010-3311

=====================================================================

 

1. Summary:

 

Updated freetype packages that fix three security issues are now available

for Red Hat Enterprise Linux 3.

 

The Red Hat Security Response Team has rated this update as having

important security impact. Common Vulnerability Scoring System (CVSS) base

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Desktop version 3 - i386, x86_64

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64

Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

 

3. Description:

 

FreeType is a free, high-quality, portable font engine that can open and

manage font files. It also loads, hints, and renders individual glyphs

efficiently. The freetype packages for Red Hat Enterprise Linux 3 provide

both the FreeType 1 and FreeType 2 font engines.

 

It was discovered that the FreeType font rendering engine improperly

validated certain position values when processing input streams. If a user

loaded a specially-crafted font file with an application linked against

FreeType, and the relevant font glyphs were subsequently rendered with the

X FreeType library (libXft), it could trigger a heap-based buffer overflow

in the libXft library, causing the application to crash or, possibly,

execute arbitrary code with the privileges of the user running the

application. (CVE-2010-3311)

 

An array index error was found in the way the FreeType font rendering

engine processed certain PostScript Type 42 font files. If a user loaded a

specially-crafted font file with an application linked against FreeType, it

could cause the application to crash or, possibly, execute arbitrary code

with the privileges of the user running the application. (CVE-2010-2806)

 

A stack overflow flaw was found in the way the FreeType font rendering

engine processed PostScript Type 1 font files that contain nested Standard

Encoding Accented Character (seac) calls. If a user loaded a

specially-crafted font file with an application linked against FreeType, it

could cause the application to crash. (CVE-2010-3054)

 

Note: All of the issues in this erratum only affect the FreeType 2 font

engine.

 

Users are advised to upgrade to these updated packages, which contain

backported patches to correct these issues. The X server must be restarted

(log out, then log back in) for this update to take effect.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to

use the Red Hat Network to apply this update are available at
