Multiple Vulnerabilities in Security Appliances and Cisco Firewall Services Module

Cisco security advisory is warning for multiple vulnerabilities in its Cisco ASA 5500 Series Adaptive Security Appliances and Cisco Firewall Services Module (FWSM) for the Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers.

Cisco ASA 5500 Series Adaptive Security Appliances are affected by multiple vulnerabilities as follows:

  • Three SunRPC Inspection Denial of Service Vulnerabilities
  • Three Transport Layer Security (TLS) Denial of Service Vulnerabilities
  • Session Initiation Protocol (SIP) Inspection Denial of Service Vulnerability
  • Crafted Internet Key Exchange (IKE) Message Denial of Service Vulnerability

Multiple vulnerabilities exist in the Cisco Firewall Services Module (FWSM) for the Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers that may cause the Cisco FWSM to reload after processing crafted SunRPC or certain TCP packets. Repeated exploitation could result in a sustained DoS condition. Cisco has released free software updates that address these vulnerabilities.
