+commit 6045de69c7dedcba3eadf7c4bba424b19c81d00d
+Author: Stanislav Malyshev <stas@php.net>
+Date: Sun Oct 23 20:07:47 2016 -0700
+
+ Fix bug #73331 - do not try to serialize/unserialize objects wddx can not handle
+
+ Proper soltion would be to call serialize/unserialize and deal with the result,
+ but this requires more work that should be done by wddx maintainer (not me).
+
+Upstream-status: Backport
+
+CVE: CVE-2016-9934
