Synopsis :

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

Description :

Updated icu packages that fix one security issue are now available for
Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

The International Components for Unicode (ICU) library provides robust
and full-featured Unicode services.

A stack-based buffer overflow flaw was found in the way ICU performed
variant canonicalization for some locale identifiers. If a
specially-crafted locale representation was opened in an application
linked against ICU, it could cause the application to crash or,
possibly, execute arbitrary code with the privileges of the user
running the application. (CVE-2011-4599)

All users of ICU should upgrade to these updated packages, which
contain a backported patch to resolve this issue. All applications
linked against ICU must be restarted for this update to take effect.
