CentOS Errata and Security Advisory CESA-2011:1815
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.
