The PHP Development Team would like to announce the immediate release of PHP 4.3.11 and 5.0.4. These are maintenance releases that in addition to fixing over 70 non-critical bugs, address several security issues. The addressed security issues include fixes to the exif and fbsql extensions, as well as fixes to unserialize(), swf_definepoly() and getimagesize().

All users of PHP are strongly encouraged to upgrade to this release.

Aside from the above mentioned issues this release includes the following important fixes:

* Crash in bzopen() if supplied path to non-existent file.
* DOM crashing when attribute appended to Document.
* unserialize() float problem on non-English locales.
* Crash in msg_send() when non-string is stored without being serialized.
* Possible infinite loop in imap_mail_compose().
* Fixed crash in chunk_split(), when chunklen > strlen.
* session_set_save_handler crashes PHP when supplied non-existent object reference.
* Memory leak in zend_language_scanner.c.
* Compile failures of zend_strtod.c.
* Fixed crash in overloaded objects & overload() function.
* cURL functions bypass open_basedir.

The PHP Development Team would like to thank all the people who have identified the security faults in PHP and helped us address them.
