Mandriva Linux Security Advisory 2012-065
Posted Apr 27, 2012
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2012-065 - The PDORow implementation in PHP before 5.3.9 does not properly interact with the session feature, which allows remote attackers to cause a denial of service via a crafted application that uses a PDO driver for a fetch and then calls the session_start function, as demonstrated by a crash of the Apache HTTP Server. The php_register_variable_ex function in php_variables.c in PHP 5.3.9 allows remote attackers to execute arbitrary code via a request containing a large number of variables, related to improper handling of array variables. PHP before 5.3.10 does not properly perform a temporary change to the magic_quotes_gpc directive during the importing of environment variables, which makes it easier for remote attackers to conduct SQL injection attacks via a crafted request, related to main/php_variables.c, sapi/cgi/cgi_main.c, and sapi/fpm/fpm/fpm_main.c. Insufficient validating of upload name leading to corrupted $_FILES indices. Various other issues have also been addressed.

Ubuntu Security Notice USN-1358-1
Posted Feb 10, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1358-1 - It was discovered that PHP computed hash values for form parameters without restricting the ability to trigger hash collisions predictably. This could allow a remote attacker to cause a denial of service by sending many crafted parameters. ATTENTION: this update changes previous PHP behavior by limiting the number of external input variables to 1000. This may be increased by adding a "max_input_vars" directive to the php.ini configuration file. See http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars for more information. Various other issues were also addressed.

Red Hat Security Advisory 2012-0093-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was discovered that the fix for CVE-2011-4885 introduced an uninitialized memory use flaw. A remote attacker could send a specially-crafted HTTP request to cause the PHP interpreter to crash or, possibly, execute arbitrary code. 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.
