var-201407-0385
Vulnerability from variot
Cisco IOS XR 4.3(.2) and earlier on ASR 9000 devices does not properly perform NetFlow sampling of IP packets, which allows remote attackers to cause a denial of service (chip and card hangs) via malformed (1) IPv4 or (2) IPv6 packets, aka Bug ID CSCuo68417. Cisco IOS XR is a member of the Cisco IOS Software family that uses a microkernel-based operating system architecture. Attackers can exploit this issue to cause the NP chip and a line card on an affected device to lock up and reload, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuo68417. The vulnerability is caused by the fact that the program does not perform sampling of NetFlow IP packets
