Description:
A weakness and a vulnerability have been reported in PHP 5, which can be exploited by malicious, local users to bypass certain security restrictions.
1) An integer overflow error in the "chunk_split()" function can be exploited to cause a heap based buffer overflow.
Successful exploitation of this vulnerability may allow execution of arbitrary code, which can lead to security restrictions, such as the "disable_functions" directive, being bypassed.
2) An error in the "realpath()" function allows bypassing of the "open_basedir" restriction and identifying the existence of files.
