View PHP related news. The PHP development team would like to announce the immediate availability of PHP 5.2.1 and availability of PHP 4.4.5. These releases are major stability and security enhancements of the 5.x and 4.4.x branches, and all users are strongly encouraged to upgrade to it as soon as possible. Further details about the PHP 5.2.1 release can be found in the release announcement for 5.2.1, the full list of changes is available in the ChangeLog for PHP 5. Details about the PHP 4.4.5 release can be found in the release announcement for 4.4.5, the full list of changes is available in the ChangeLog for PHP 4. Security Enhancements and Fixes in PHP 5.2.1 and PHP 4.4.5: Fixed possible safe_mode & open_basedir bypasses inside the session extension. Fixed unserialize() abuse on 64 bit systems with certain input strings. Fixed possible overflows and stack corruptions in the session extension.

Fixed possible clobbering of super-globals in several code paths. Fixed a possible information disclosure inside the wddx extension. Fixed a possible string format vulnerability in *print() functions on 64 bit systems. Fixed a possible buffer overflow inside ibase_{delete,add,modify}_user() functions. Fixed a string format vulnerability inside the odbc_result_all() function. Security Enhancements and Fixes in PHP 5.2.1 only: Prevent search engines from indexing the phpinfo() page.

However, some of the above issues can be triggered remotely in certain situations, or exploited by malicious local users on shared hosting setups utilizing PHP as an Apache module. Therefore, we strongly advise all users of PHP, regardless of the version to upgrade to the 5.2.1 or 4.4.5 releases as soon as possible. For users upgrading to PHP 5.2 from PHP 5.0 and PHP 5.1, an upgrade guide is available here, detailing the changes between those releases and PHP 5.2.1.
