PHP 4.4.1. Release Announcement

The PHP Development Team would like to announce the immediate release of PHP 4.4.1.

This is a bug fix release, which addresses some security problems too.

The security issues that this release fixes are:

Fixed a Cross Site Scripting (XSS) vulnerability in phpinfo() that could lead f.e. to cookie exposure, when a phpinfo() script is accidently left on a production server.
Reference: http://www.hardened-php.net/advisory_182005.77.html

Fixed multiple safe_mode/open_basedir bypass vulnerabilities in ext/curl and ext/gd that could lead to exposure of files normally not accessible due to safe_mode or open_basedir restrictions.

Fixed a possible $GLOBALS overwrite problem in file upload handling, extract() and import_request_variables() that could lead to unexpected security holes in scripts assumed secure. (For more information, see here).
Reference: http://www.hardened-php.net/advisory_202005.79.html

Fixed a problem when a request was terminated due to memory_limit constraints during certain parse_str() calls. In some cases this can result in register_globals being turned on.Fixed an issue with trailing slashes in allowed basedirs. They were ignored by open_basedir checks, so that specified basedirs were handled as prefixes and not as full directory names.
Reference: http://www.hardened-php.net/advisory_192005.78.html

Fixed an issue with calling virtual() on Apache 2. This allowed bypassing of certain configuration directives like safe_mode or open_basedir. Updated to the latest pcrelib to fix a possible integer overflow vulnerability announced in CAN-2005-2491.

This release also fixes 35 other defects, where the most important is the the fix that removes a notice when passing a by-reference result of a function as a by-reference value to another function. (Bug #33558).
