Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated freetype packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6.

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.

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. These packages provide the FreeType 2 font engine.

It was found 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, it could cause the application to crash or,
possibly, execute arbitrary code with the privileges of the user
running the application. (CVE-2010-2805, CVE-2010-3311)

A stack-based buffer overflow flaw was found in the way the FreeType
font rendering engine processed some PostScript Type 1 fonts. 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-2010-2808)

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)

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.
