In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, lack of a bounds check in the date extension's timelib_meridian parsing code could be used by attackers able to supply date strings to leak information from the interpreter, related to an ext/date/lib/parse_date.c out-of-bounds read affecting the php_parse_date function.

Created php tracking bugs for this issue: Affects: fedora-all [bug 1471856]
This issue happens when untrusted input is deserialized. Doing so is documented as being unsafe: http://php.net/manual/en/function.wddx-deserialize.php Do not pass untrusted user input to wddx_deserialize(). Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (via json_decode() and json_encode()) if you need to pass serialized data to the user.
The CVE-2017-11146 was rejected as: """ This candidate was withdrawn by its CNA. Further investigation showed that it was not an independently fixable security issue relative to CVE-2017-11145. """
