cisco-sa-20100827-bgp: Cisco IOS XR Software Border Gateway Protocol Vulnerability

Affected Products ================= This vulnerability affects all Cisco IOS XR Software devices configured with BGP routing.

Details ======= This vulnerability affects Cisco IOS XR devices running affected software versions and configured with the BGP routing feature. 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. Read more at www.criticalwatch.com
