Cisco IOS IPv6 Source Routing Remote Memory Corruption Vulnerability

Cisco IOS is prone to a remote memory-corruption vulnerability because the software fails to properly handle malformed IPv6 source-routing headers.

Successfully exploiting this issue allows remote attackers to corrupt the memory of affected devices. This may potentially facilitate the execution of attacker-supplied machine code. Failed exploit attempts will likely crash IOS-based devices.

This issue is being tracked by Cisco Bug IDs CSCsd40334 and CSCsd58381.
