I just released gentoo-sources 2.6.32-r14, 2.6.34-r6 and 2.6.35-r2. These all include the patch for the local privilege escalation flaw bug that was recently announced. So, I do recommended all gentoo-sources users upgrade to these latest versions.
There is also a bug fix included for people that were experiencing the freeze/oops in 18.104.22.168 as referenced in this bug.
Please note that 2.6.33 is no longer being supported by Gentoo-Sources.
