CVE-2015-3411

PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not
ensure that pathnames lack %00 sequences, which might allow remote
attackers to read or write to arbitrary files via crafted input to an
application that calls (1) a DOMDocument load method, (2) the
xmlwriter_open_uri function, (3) the finfo_file function, or (4) the
hash_hmac_file function, as demonstrated by a filename\0.xml attack that
bypasses an intended configuration in which client users may read only .xml
files.
