Description:
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 error in the handling of null byte characters in the "curl_init()" PHP function in the curl extension. This can be exploited to bypass the safe mode protection and access other users' files located in the same directory as the running script.
Successful exploitation requires that the curl extension is installed and enabled.
The weakness has been confirmed in versions 5.0.5 and 5.1.4, and has also been reported in version 4.4.2. Other versions may also be affected.
