I have recently been put in charge of keeping an eye on the servers (we don't have a server admin) and I just realized that we are running a pretty old version of php which has multiple vulnerabilities according to http://lwn.net/Alerts/609952/. I would like to update to the latest stable version but I'm not sure if there's anything else I should do besides these 2 commands:
emerge --sync emerge --ask --oneshot --verbose "=dev-lang/php-5.5.17
Do I have to recompile php? is there any other step to get it working with apache?
I would really appreciate some help as I'm not very familiar with Gentoo.
