On July 10th 2015, the PHP group released PHP 5.6.11.
Five security-related issues in PHP were fixed in this release, including CVE-2015-3152. All PHP 5.6 users are encouraged to upgrade to this version.
PHP 5.6.11 packages are now available for Debian 7 “Wheezy”, on both amd64 and i386 architectures, in ZTS and non-ZTS (default) flavors, along with the usual PECL extensions.
Note : php5-memcached still lacks JSON support.
