The remote device is missing a vendor-supplied security patch.
A vulnerability in the T1/E1 driver queue implementation of Cisco IOS
Software could allow an unauthenticated, remote attacker to cause an
interface wedge condition, which could lead to loss of connectivity,
loss of routing protocol adjacency, and could result in a denial of
service (DoS) scenario. The vulnerability is due to incorrect
implementation of the T1/E1 driver queue. An attacker could exploit
this vulnerability by sending bursty traffic through the affected
interface driver. Repeated exploitation could cause a DoS condition.
Workarounds to mitigate this vulnerability are available. Cisco has
released free software updates that address this vulnerability.
