Bugfix and security release:
Fixed bug #68283 (fileinfo: out-of-bounds read in elf note headers). (CVE-2014-3710)
I've been running these on 20 servers since the release on amd64.
On a newly installed machine I encountered a problem with reloading php-fpm instances (https://bugs.gentoo.org/show_bug.cgi?id=531354).
5.5.20 is RC1 with some fixes regarding PHP-FPM (https://github.com/php/php-src/blob/PHP-5.5.20/NEWS)
Added to existing GLSA. Putting in cleanup state due to PHP 5.3 still being in tree.
Cleanup would be done in bug #533998
