Php · Php · CVE-2016-9935
**Name of the Vulnerable Software and Affected Versions**
PHP versions prior to 5.6.29
PHP versions 7.x prior to 7.0.14
**Description**
The issue is related to the php wddx push element function, which allows remote attackers to cause a denial of service or possibly have other impacts via an empty boolean element in a wddxPacket XML document. This can lead to an out-of-bounds read and memory corruption. The vulnerability is caused by a buffer overflow read.
**Recommendations**
For PHP versions prior to 5.6.29, update to version 5.6.29 or later.
For PHP versions 7.x prior to 7.0.14, update to version 7.0.14 or later.
As a temporary workaround, consider restricting the use of the php wddx push element function until a patch is available. Avoid using empty boolean elements in wddxPacket XML documents to minimize the risk of exploitation.
