Red Hat: Updated icu packages fix two security issues

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. Fixed packages are available from updates.redhat.com.
