The move_uploaded_file implementation in ext/standard/basic_functions.c in
PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 truncates a
pathname upon encountering a \x00 character, which allows remote attackers
to bypass intended extension restrictions and create files with unexpected
names via a crafted second argument. NOTE: this vulnerability exists
because of an incomplete fix for CVE-2006-7243.
