Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2010:0578 :

Updated freetype packages that fix various security issues are now
available for Red Hat Enterprise Linux 4 and 5.

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. The freetype packages for Red Hat Enterprise Linux
4 provide both the FreeType 1 and FreeType 2 font engines. The
freetype packages for Red Hat Enterprise Linux 5 provide only the
FreeType 2 font engine.

An invalid memory management flaw was found in the way the FreeType
font engine processed font files. If a user loaded a carefully-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-2010-2498)

An integer overflow flaw was found in the way the FreeType font engine
processed font files. If a user loaded a carefully-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-2010-2500)

Several buffer overflow flaws were found in the way the FreeType font
engine processed font files. If a user loaded a carefully-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-2010-2499,
CVE-2010-2519)

Several buffer overflow flaws were found in the FreeType demo
applications. If a user loaded a carefully-crafted font file with a
demo application, it could cause the application to crash or,
possibly, execute arbitrary code with the privileges of the user
running the application. (CVE-2010-2527, CVE-2010-2541)

Red Hat would like to thank Robert Swiecki of the Google Security Team
for the discovery of the CVE-2010-2498, CVE-2010-2500, CVE-2010-2499,
CVE-2010-2519, and CVE-2010-2527 issues.

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.
