Description
Cisco Adaptive Security Appliance (ASA) Software 8.4.x before 8.4(3) and 8.6.x before 8.6(1.3) does not properly manage memory upon an AnyConnect SSL VPN client disconnection, which allows remote attackers to cause a denial of service (memory consumption, and forwarding outage or system hang) via packets to the disconnected machine's IP address, aka Bug ID CSCtt36737.
