Hello, yes it still can be safe to use linux kernel 2.6.34.
The exploit you reference need the attacker to have a local system account to perform this attack. (ssh access)
This is certainly not the case.
What make you think you are infected ?

Kernel 2.6.34 (pure from kernel.org) is not very secure.
Do you have full version of it (uname -r)?

Whenever you use a proper firewall and your apache server is up to date
+ if you only let http port open, i doubt that this kernel would be a problem.

Anybody can consume all system RAM via CVE-2012-6638, firewall or not.
Thats one I remember, plus 100 others lost in time.
If you are patching from whichever still supported source 2.6.34-(whatever number) should be very good for any purpose

2.6.34-12-desktop
uname -a
Linux opensuse 2.6.34-12-desktop #1 SMP PREEMPT 2010-06-29 02:39:08 +0200 x86_64 x86_64 x86_64 GNU/Linux  

How to patch that? maybe just update kernel? if I update it to the newest kernel could it cause any inconsistency in userspace programs behaviour? in FreeBSD I need to get updated both kernel + us + ports, what about suse?

It is OpenSUSE 11.3 , EOL
You can update to 11.4 evergreen
Or jump to 13.1 which will be evergreen
You can upgrade OpenSUSE with 4GB full install DVD ONLY
(Why not unify your platforms on FreeBSD, or CentOS, or opensuse evergreen for instance)

On the pretext that it is unmaintainable at least get it to FreeBSD -RELENG releases, CentOS&Fedora to CentOS 5 or 6 or 7-latest and OpenSUSE to evergreen release thet follows installed one.
At least you & company will have good oversight what is in the server room.

If you run typical apache and tomcat on 20 servers, maybe make load-balance cluster of two linux servers and 10 applications... You gain stability, 99.9% availability and 8 systems off your hands...
