Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated php packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical 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.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

A flaw was found in the way the php-cgi executable processed command line arguments when running in CGI mode. A remote attacker could send a specially crafted request to a PHP script that would result in the query string being parsed by php-cgi as command line options and arguments. This could lead to the disclosure of the script's source code or arbitrary code execution with the privileges of the PHP interpreter. (CVE-2012-1823)

Red Hat is aware that a public exploit for this issue is available that allows remote code execution in affected PHP CGI configurations.
This flaw does not affect the default configuration in Red Hat Enterprise Linux 5 and 6 using the PHP module for Apache httpd to handle PHP scripts.

All php users should upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

Solution

Update the affected php packages.
