The AAA functionality in the IPv4 SSL VPN implementations on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 8.2 before 8.2(5.30) and 8.3 before 8.3(2.34) allows remote attackers to cause a denial of service (device reload) via a crafted authentication response, aka Bug ID CSCtz04566.

Cisco AnyConnect Secure Mobility Client 3.0 through 3.0.08066 does not ensure that authentication makes use of a legitimate certificate, which allows user-assisted man-in-the-middle attackers to spoof servers via a crafted certificate, aka Bug ID CSCtz29197.

dot11t/t_if_dot11_hal_ath.c in Cisco IOS 12.3, 12.4, 15.0, and 15.1 allows remote attackers to cause a denial of service (assertion failure and reboot) via 802.11 wireless traffic, as demonstrated by a video call from Apple iOS 5.0 on an iPhone 4S, aka Bug ID CSCtt94391.

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.2 through 8.4 do not properly perform proxy authentication during attempts to cut through a firewall, which allows remote attackers to obtain sensitive information via a connection attempt, aka Bug ID CSCtx42746.

Cisco Small Business IP phones with SPA 500 series firmware 7.4.9 and earlier do not require authentication for Push XML requests, which allows remote attackers to make telephone calls via an XML document, aka Bug ID CSCts08768.

The sensor in Cisco Intrusion Prevention System (IPS) 7.0 and 7.1 allows remote attackers to cause a denial of service (file-handle exhaustion and mainApp hang) by making authentication attempts that exceed the configured limit, aka Bug ID CSCto51204.

The PPP implementation in Cisco IOS 12.2 and 15.0 through 15.2, when Point-to-Point Termination and Aggregation (PTA) and L2TP are used, allows remote attackers to cause a denial of service (device crash) via crafted network traffic, aka Bug ID CSCtf71673.
