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

"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."
