The remote device is missing a vendor-supplied security patch.
Cisco routers and switches running Cisco IOS or Cisco IOS XR software
may be vulnerable to a remotely exploitable crafted IP option Denial of
Service (DoS) attack. Exploitation of the vulnerability may potentially
allow for arbitrary code execution. The vulnerability may be exploited
after processing an Internet Control Message Protocol (ICMP) packet,
Protocol Independent Multicast version 2 (PIMv2) packet, Pragmatic
General Multicast (PGM) packet, or URL Rendezvous Directory (URD)
packet containing a specific crafted IP option in the packet's IP
header. No other IP protocols are affected by this issue.
Cisco has made free software available to address this vulnerability
for affected customers.
