PHP Data Processing Errors Vulnerability - CVE-2015-4025
PHP before 5.4.41 5.5.x before 5.5.25 and 5.6.x before 5.6.9 truncates a pathname upon encountering a x00 character in certain situations which allows remote attackers to bypass intended extension restrictions and access files or directories with unexpected names via a crafted argument to (1) set_include_path (2) tempnam (3) rmdir or (4) readlink. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243.
