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.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.
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.
NoteThe 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.
