Latest php-pecl-apc updates resolve security issues while providing improvements for CentOS and Fedora distributions.
Updated php-pecl-apc packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

The php-pecl-apc packages contain APC (Alternative PHP Cache), the framework for caching and optimization of intermediate PHP code.
A cross-site scripting (XSS) flaw was found in the "apc.php" script, which provides a detailed analysis of the internal workings of APC and is shipped as part of the APC extension documentation. A remote attacker could possibly use this flaw to conduct a cross-site scripting attack. (CVE-2010-3294)
Note: The administrative script is not deployed upon package installation. It must manually be copied to the web root (the default is "/var/www/html/", for example).
In addition, the php-pecl-apc packages have been upgraded to upstream version 3.1.9, which provides a number of bug fixes and enhancements over the previous version. (BZ#662655)
All users of php-pecl-apc are advised to upgrade to these updated packages, which fix these issues and add these enhancements. If the "apc.php" script was previously deployed in the web root, it must manually be re-deployed to replace the vulnerable version to resolve this issue.
