Maksymilian Arciemowicz has discovered a weakness in PHP, which can be exploited by malicious, local users to bypass certain security restrictions.
The weakness is caused due to an input validation error in the "error_log()" PHP function in the processing of the destination parameter. This can be exploited to bypass the safe mode protection via directory traversal attacks in the "php://" wrapper.
The weakness has been confirmed in version 5.1.4 and has also been reported in version 4.4.2. Other versions may also be affected.
