- CVE-2016-9935 (denial of service)

The php_wddx_push_element function in ext/wddx/wddx.c in PHP before
5.6.29 and 7.x before 7.0.14 allows remote attackers to cause a denial
of service (out-of-bounds read and memory corruption) or possibly have
unspecified other impact via an empty boolean element in a wddxPacket
XML document.

- CVE-2016-9936 (arbitrary code execution)

The unserialize implementation in ext/standard/var.c in PHP 7.x before
7.0.14 allows remote attackers to cause a denial of service (use-after-
free) or possibly execute arbitrary code via crafted serialized data.

- CVE-2017-5340 (arbitrary code execution)

It was found that PHP uses uninitialized memory during calls to
`unserialize()`. The payload supplied to `unserialize()` may control
this uninitialized memory region and thus may be used to trick PHP into
operating on faked objects and calling attacker controlled destructor
function pointers, effectively allowing arbitrary code execution via
specially crafted serialized data.


A remote attacker is able to use specially crafted input to perform a
denial of service attack or execute arbitrary code on the affected
