Recently added a 2811 router to our network, and I was informed about this advisory "Advisory ID: cisco-sa-20090908-tcp24".

We are running Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(22)T, RELEASE SOFTWARE (fc1)

I'm not sure if I understanding the fixed release vs. the recommended release correctly. I did not see any mention of the release we are using.

Is Version 12.4(22)T, RELEASE SOFTWARE (fc1) covered for this advisory?

Yes, it is. The first fixed release is 12.4(22)T1, but the recommended upgrade is to 12.4(22)T3.
