Detail

Cisco ASA 5500 Series Adaptive Security Appliances (ASA) and Cisco Catalyst 6500 Series ASA Services Module (ASASM) may be affected by the following vulnerabilities:

DHCP Memory Allocation Denial of Service Vulnerability SSL VPN Authentication Denial of Service Vulnerability SIP Inspection Media Update Denial of Service Vulnerability DCERPC Inspection Buffer Overflow Vulnerability Two DCERPC Inspection Denial Of Service Vulnerabilities

These vulnerabilities are independent of each other; a release that is affected by one of the vulnerabilities may not be affected by the others.

Successful exploitation of any of these vulnerabilities could allow an unauthenticated remote attacker to trigger a reload of the affected device. Exploitation of the DCERPC Inspection Buffer Overflow Vulnerability could additionally cause a stack overflow and possibly the execution of arbitrary commands.

Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of these vulnerabilities. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20121010-asa

Note: The Cisco Firewall Services Module for Cisco Catalyst 6500 and Cisco 7600 Series (FWSM) may be affected by some of the vulnerabilities listed above. A separate Cisco Security Advisory has been published to disclose the vulnerabilities that affect the Cisco FWSM. This advisory is available at: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20121010-fwsm

The Cisco ASA 1000V Cloud Firewall and Cisco ASA-CX Context-Aware Security are not affected by any of these vulnerabilities. BEGIN PGP SIGNATURE Version: GnuPG/MacGPG2 v2.0.18 (Darwin) Comment: GPGTools - http://gpgtools.org
