RHSA-2008:0090 - Security Advisory

Synopsis

Important: icu security update

Type/Severity

Security Advisory: Important

Topic

Updated icu packages that fix two security issues are now available for Red
Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

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

Will Drewry reported multiple flaws in the way libicu processed certain
malformed regular expressions. If an application linked against ICU, such
as OpenOffice.org, processed a carefully crafted regular expression, it may
be possible to execute arbitrary code as the user running the application.
(CVE-2007-4770, CVE-2007-4771)

All users of icu should upgrade to these updated packages, which contain
backported patches to resolve these issues.

Solution

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