CVE-2016-7418
CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.6.26
PHP 7.x versions prior to 7.0.11
Description
The issue allows remote attackers to cause a denial of service or possibly have other unspecified impacts through an incorrect boolean element in a wddxPacket XML document. This leads to mishandling in a
wddx deserialize call, resulting in invalid pointer access and out-of-bounds read. The problem is caused by a buffer overflow in the php wddx push element function.Recommendations
For PHP versions prior to 5.6.26, update to version 5.6.26 or later.
For PHP 7.x versions prior to 7.0.11, update to version 7.0.11 or later.
As a temporary workaround, consider restricting the use of the
php wddx push element function until a patch is available. Avoid using incorrect boolean elements in wddxPacket XML documents to minimize the risk of exploitation.Exploit
