Detail

A vulnerability in the TCP input module of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak and eventual reload of the affected device.

The vulnerability is due to improper handling of certain crafted packet sequences used in establishing a TCP three-way handshake. An attacker could exploit this vulnerability by sending a crafted sequence of TCP packets while establishing a three-way handshake. A successful exploit could allow the attacker to cause a memory leak and eventual reload of the affected device.

Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available.
