RHEL 5 / 6 : php (RHSA-2012:0546)

critical Nessus Plugin ID 59030

Language:

Synopsis

The remote Red Hat host is missing a security update for php.

Description

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0546 advisory.

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL php package based on the guidance in RHSA-2012:0546.
