Cisco Adaptive Security Appliance (ASA) software 7.2 and 8.2 before 8.2(5.58), 8.3 and 8.4 before 8.4(7.29), 8.5 through 8.7 before 8.7(1.17), 9.0 before 9.0(4.37), 9.1 before 9.1(6.4), 9.2 before 9.2(4), 9.3 before 9.3(3.1), and 9.4 before 9.4(1.1) allows remote attackers to cause a denial of service (device reload) via a crafted DNS response, aka Bug ID CSCut03495.

The DHCPv6 relay implementation in Cisco Adaptive Security Appliance (ASA) software 9.0 before 9.0(4.37), 9.1 before 9.1(6.6), 9.2 before 9.2(4), 9.3 before 9.3(3.5), and 9.4 before 9.4(2) allows remote attackers to cause a denial of service (device reload) via crafted DHCPv6 packets, aka Bug IDs CSCus56252 and CSCus57142.

The Unicast Reverse Path Forwarding (uRPF) implementation in Cisco Adaptive Security Appliance (ASA) Software 9.3(1.50), 9.3(2.100), 9.3(3), and 9.4(1) mishandles cases where an IP address belongs to an internal interface but is also in the ASA routing table, which allows remote attackers to bypass uRPF validation via spoofed packets, aka Bug ID CSCuv60724.

The TLS implementation in the Cavium cryptographic-module firmware, as distributed with Cisco Adaptive Security Appliance (ASA) Software 9.1(5.21) and other products, does not verify the MAC field, which allows man-in-the-middle attackers to spoof TLS content by modifying packets, aka Bug ID CSCuu52976.

Cisco Adaptive Security Appliance (ASA) Software 9.3(2) allows remote attackers to cause a denial of service (system reload) by sending crafted OSPFv2 packets on the local network, aka Bug ID CSCut52679.

Cisco Adaptive Security Appliance (ASA) Software 9.3(2.243) and 100.13(0.21) allows remote attackers to cause a denial of service (device reload) by sending crafted OSPFv2 packets on the local network, aka Bug ID CSCus84220.

The SNMP implementation in Cisco Adaptive Security Appliance (ASA) Software 8.4(7) and 8.6(1.2) allows remote authenticated users to cause a denial of service (device reload) by sending many SNMP requests during a time of high network traffic, aka Bug ID CSCul02601.

The Cavium cryptographic-module firmware on Cisco Adaptive Security Appliance (ASA) devices with software 9.3(3) and 9.4(1.1) does not verify the AES-GCM Integrity Check Value (ICV) octets, which makes it easier for man-in-the-middle attackers to spoof IPSec and IKEv2 traffic by modifying packet data, aka Bug ID CSCuu66218.

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.
