Scientific Linux Security Update : php on SL5.x, SL6.x i386/x86_64
High Nessus Plugin ID 61312
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionPHP 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 in Scientific 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.
SolutionUpdate the affected packages.
