Scientific Linux Security Update : php53 on SL5.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

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)

Scientific Linux 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
using the PHP module for Apache httpd to handle PHP scripts.

All php53 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.
