This patch was to address a root exploit on the new RH5 Kernel 2.6.17 - 2.6.24.1. More information here:

http://www.securityfocus.com/bid/27704/info

There were 2 servers that is running this kernel but has not been compromised:

cwh5
cpres3

We did an emergency patch on these servers this morning which took less than 30 mins. cpres3 had a little problem coming back up but it was resolved after a fsck was performed.

Many hosting companies have already reported being hacked which affected service to many customers. We seem to have adverted what could have been a very, very bad day!

Would this also cause some mbstring problems with PHP?

For some reason, I keep getting "Fatal error: Unknown function: mb_internal_encoding()" on one of my boards now. Since the string seem to be an old way for PHP to handle UTF-8 encoding, I was wondering if this is a result from the patching?

Other boards I'm running from my account dont seem to be affected.

Hello,

We have enabled mbstring module in the server.
