IOS Heap Overflow Advisory

[schroednet]

Hi all;

I became aware of this advisory and wonder if a patch/update is appplicable or necessary.

I have two 2600 series routers running 12.x vers. Here's excerpts from both:

Router 1.

IOS (tm) C2600 Software (C2600-I-M), Version 12.2(13)T5, RELEASE SOFTWARE (fc1)

Router 2.

IOS (tm) C2600 Software (C2600-I-M), Version 12.0(7)T, RELEASE SOFTWARE (fc2)

Looking through the advisory bulletin, I cannot figure out what repair release I should apply.

I also am wondering if I really need to apply any patch to begin with. I have firewalls behind these routers and run NAT and have NOT noticed any increase activity such as DOS or DDOS, etc. attacks.

Any replies would be appreciated.

Thank you,

Steve

Hi,

You should contact the Technical Assistance Center for instructions on which IOS image to use.

Even if you don't have a service contract, they will provide you with all the necessary information for free since this is a critical update.

Either email at tac@cisco and mention advisory 68064, or by phone (http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml)
