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 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.
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.
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.
The SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.3(.2) and earlier does not properly allocate memory blocks during HTTP packet handling, which allows remote attackers to cause a denial of service (memory consumption) via crafted packets, aka Bug ID CSCuq68888.
The SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.2(.2.4) and earlier does not properly manage session information during creation of a SharePoint handler, which allows remote authenticated users to overwrite arbitrary RAMFS cache files or inject Lua programs, and consequently cause a denial of service (portal outage or system reload), via crafted HTTP requests, aka Bug ID CSCup54208.
Cisco Adaptive Security Appliance (ASA) Software 9.1(.5) and earlier allows remote authenticated users to cause a denial of service (device reload) via crafted attributes in a RADIUS packet, aka Bug ID CSCun69561.
