On April 30th 2014, the PHP group has released PHP 5.5.12 :
This release fixes several bugs against PHP 5.5.11, as well as CVE-2014-0185 regarding PHP-FPM. All PHP users are encouraged to upgrade to this new version.
As a consequence, PHP 5.5.12 packages are now available on Dotdeb for Debian 7.4 “Wheezy”, on both amd64 and i386 architectures.
Please note that if you’re using an Unix socket to make PHP-FPM talk to your web server, you’ll have to set the listen.owner and listen.group directive to the right user/group (usually www-data), for each of your pool. Don’t change the permissions on the socket from 0660 to 0666 (too permissive), it would avoid the CVE-2014-0185 fix.
And don’t forget: if you find Dotdeb useful, you may want to show your support.
