The cisco case involved :
Short detail from the Cisco site:
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.
Could you provide insight in why you are specifically looking for a Cisco
IOS bug that has taken down a network ?
