The IKEv1 implementation in Cisco ASA Software 7.x, 8.0.x, 8.1.x, and 8.2.x before 8.2.2.13 allows remote authenticated users to bypass XAUTH authentication via crafted IKEv1 packets, aka Bug ID CSCus47259.
The Protocol Independent Multicast (PIM) application in Cisco Adaptive Security Appliance (ASA) Software 9.2(0.0), 9.2(0.104), 9.2(3.1), 9.2(3.4), 9.3(1.105), 9.3(2.100), 9.4(0.115), 100.13(0.21), 100.13(20.3), 100.13(21.9), and 100.14(1.1) does not properly implement multicast-forwarding registration, which allows remote attackers to cause a denial of service (forwarding outage) via a crafted multicast packet, aka Bug ID CSCus74398.
The XML parser in Cisco Adaptive Security Appliance (ASA) Software 8.4 before 8.4(7.28), 8.6 before 8.6(1.17), 9.0 before 9.0(4.33), 9.1 before 9.1(6), 9.2 before 9.2(3.4), and 9.3 before 9.3(3), when Clientless SSL VPN, AnyConnect SSL VPN, or AnyConnect IKEv2 VPN is used, allows remote attackers to cause a denial of service (VPN outage or device reload) via a crafted XML document, aka Bug ID CSCus95290.
The DNS implementation in Cisco Adaptive Security Appliance (ASA) Software 7.2 before 7.2(5.16), 8.2 before 8.2(5.57), 8.3 before 8.3(2.44), 8.4 before 8.4(7.28), 8.5 before 8.5(1.24), 8.6 before 8.6(1.17), 8.7 before 8.7(1.16), 9.0 before 9.0(4.33), 9.1 before 9.1(6.1), 9.2 before 9.2(3.4), and 9.3 before 9.3(3) allows man-in-the-middle attackers to cause a denial of service (memory consumption or device outage) by triggering outbound DNS queries and then sending crafted responses to these queries, aka Bug ID CSCuq77655.
The failover ipsec implementation in Cisco Adaptive Security Appliance (ASA) Software 9.1 before 9.1(6), 9.2 before 9.2(3.3), and 9.3 before 9.3(3) does not properly validate failover communication messages, which allows remote attackers to reconfigure an ASA device, and consequently obtain administrative control, by sending crafted UDP packets over the local network to the failover interface, aka Bug ID CSCur21069.
Cisco Adaptive Security Appliance (ASA) Software 9.2(.3) and earlier, when challenge-response authentication is used, does not properly select tunnel groups, which allows remote authenticated users to bypass intended resource-access restrictions via a crafted tunnel-group parameter, aka Bug ID CSCtz48533.
Memory leak in the embedded web server in the WebVPN subsystem in Cisco Adaptive Security Appliance (ASA) Software allows remote attackers to cause a denial of service (memory consumption and SSL outage) via multiple crafted HTTP requests, aka Bug ID CSCue05458.
The Proxy Bypass Content Rewriter feature in the WebVPN subsystem in Cisco Adaptive Security Appliance (ASA) Software 9.1(.2) and earlier allows remote authenticated users to cause a denial of service (device crash or error-recovery event) via an HTTP request that triggers a rewrite, aka Bug ID CSCug91577.
Cisco Adaptive Security Appliance (ASA) Software, when a DHCPv6 relay is configured, allows remote attackers to cause a denial of service (device reload) via crafted DHCP packets on the local network, aka Bug ID CSCur45455.
The syslog-management subsystem in Cisco Adaptive Security Appliance (ASA) Software allows remote attackers to obtain an administrator password by waiting for an administrator to copy a file, and then (1) sniffing the network for a syslog message or (2) reading a syslog message in a file on a syslog server, aka Bug IDs CSCuq22357 and CSCur41860.
