Oracle Linux 5 / 6 : php (ELSA-2012-0546)

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2012:0546 :

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.
