RHSA-2011:1815 - Security Advisory

Synopsis

Moderate: icu security update

Type/Severity

Security Advisory: Moderate

Topic

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.

Description

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.

Solution

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