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.
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.
