Cisco Security Advisory: Multiple Vulnerabilities in Cisco IPS Software
Advisory ID: cisco-sa-20140219-ips
Revision 1.0
For Public Release 2014 February 19 16:00 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
Cisco Intrusion Prevention System (IPS) Software is affected by the following
vulnerabilities:
Cisco IPS Analysis Engine Denial of Service Vulnerability
Cisco IPS Control-Plane MainApp Denial of Service Vulnerability
Cisco IPS Jumbo Frame Denial of Service Vulnerability
The Cisco IPS Analysis Engine Denial of Service Vulnerability and the Cisco IPS
Jumbo Frame Denial of Service Vulnerability could allow an unauthenticated,
remote attacker to cause the Analysis Engine process to become unresponsive or
crash. When this occurs, the Cisco IPS will stop inspecting traffic.
The Cisco IPS Control-Plane MainApp Denial of Service Vulnerability could allow
an unauthenticated, remote attacker to cause the MainApp process to become
unresponsive and prevent it from executing several tasks including alert
notification, event store management, and sensor authentication. The Cisco IPS
web server will also be unavailable while the MainApp process is unresponsive,
and other processes such as the Analysis Engine process may not work properly.
Cisco has released free software updates that address these vulnerabilities.
Workarounds that mitigate some of the vulnerabilities are available. This
advisory is available at the following link:
