On June 6th 2013, the PHP group has released PHP 5.3.26.
These releases fix about 15 bugs, including CVE-2013-2110. All users of PHP are encouraged to upgrade to PHP 5.4.16.
The corresponding packages are now available on Dotdeb for Debian 6.0 “Squeeze”, on both amd64 and i386 architectures.
As usual, please read the ChangeLog before upgrading and be sure to use to the latest packages before reporting any issue.
And if you like Dotdeb, feel free to show your support.
