"A vulnerability in the implementation of the virtual fragmentation
reassembly (VFR) feature for IP version 6 (IPv6) in Cisco IOS Software
could allow an unauthenticated, remote attacker to cause an affected
device to hang or reload, resulting in a denial of service (DoS)
condition. The vulnerability is due to a race condition while
accessing the reassembly queue for IPv6 fragments. An attacker could
exploit this vulnerability by sending a crafted stream of valid IPv6
fragments. Repeated exploitation may result in a sustained DoS
condition. Cisco has released free software updates that address this
vulnerability. There are no workarounds for this vulnerability."
