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.
