Detail
| Problem Description: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5. Bugs fixed (http://bugzilla.redhat.com/): 429023 - CVE-2007-4770 libicu poor back reference validation 429025 - CVE-2007-4771 libicu incomplete interval handling |
