Not sure if the link was posted allready ... http://www.cisco.com/en/US/products/products_security_advisory09186a0080b4411f.shtml
Cisco posts their advisories to the NANOG list.
'The vulnerability manifests itself when a BGP peer announces a prefix with a specific, valid but unrecognized transitive attribute. On receipt of this prefix, the Cisco IOS XR device will corrupt the attribute before sending it to the neighboring devices. Neighboring devices that receive this corrupted update may reset the BGP peering session.'
I'm not sure what you intend to say by quoting this part of the advisory. If you think that it's an IOS XR bug which only needs fixing in IOS XR, you're showing the very attitude which has stopped us from making the network more resilient to these types of events.
