                   Red Hat Security Advisory

Synopsis:          Low: php-pecl-apc security, bug fix, and enhancement update
Advisory ID:       RHSA-2012:0811-04
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-0811.html
Issue date:        2012-06-20
CVE Names:         CVE-2010-3294 
=====================================================================

1. Summary:

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 from the CVE link in
the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

3. Description:

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.

4. 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/knowledge/articles/11258
