-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Ironport Appliances Sophos Anti-virus Vulnerabilities Advisory ID: cisco-sa-20121108-sophos Revision 1.0 For Public Release 2012 November 9 03:00 UTC (GMT) - ---------------------------------------------------------------------- Summary ======= Cisco IronPort Email Security Appliances (ESA) and Cisco IronPort Web Security Appliances (WSA) include versions of Sophos Anti-Virus that contain multiple vulnerabilities that could allow an unauthenticated, remote attacker to gain control of the system, escalate privileges, or cause a denial-of-service (DoS) condition. An attacker could exploit these vulnerabilities by sending malformed files to an appliance that is running Sophos Anti-Virus. The malformed files could cause the Sophos antivirus engine to behave unexpectedly. As updates that address these vulnerabilities become available from Sophos, Cisco is working to qualify and automatically provision them through the Cisco Ironport ESA and WSA platforms. A workaround that mitigates these vulnerabilities is available.
