CVE-2016-7478

Zend/zend_exceptions.c in PHP allows remote attackers to cause a denial of service (infinite loop) via a crafted Exception object in serialized data, a related issue to CVE-2015-8876.

CVE-2016-7479

During the unserialization process, resizing the properties hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain the ability of arbitrary code execution. Even though the property table issue only affects PHP 7 this change also prevents a wide range of other __wakeup() based attacks.

CVE-2017-7272

The fsockopen() function will use the port number which is defined in hostname instead of the port number passed to the second parameter of the function. This misbehavior may introduce another attack vector for an already known application vulnerability (e.g. Server Side Request Forgery).

For Debian 7 Wheezy, these problems have been fixed in version 5.4.45-0+deb7u8.

We recommend that you upgrade your php5 packages.
