f0e3f2a3522dbb09758f1bf08f0d15a04e639581a43300707f483dc4b76ee08aUbuntu 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.

Raphael Geisert and Dan Rosenberg discovered that the PEAR installer allows local users to overwrite arbitrary files via a symlink attack on the package.xml file. Martin Barbella discovered a buffer overflow in the PHP GD extension that allows an attacker to cause a denial of service (application crash) via a large number of anti-aliasing steps in an argument to the imagepstext function. It was discovered that PHP accepts the \0 character in a pathname, which might allow an attacker to bypass intended access restrictions by placing a safe file extension after this character. Various other issues with PHP 5 were also identified and resolved.
