Cisco Adaptive Security Appliances (ASA) devices with software 7.x before 7.2(5.10), 8.0 before 8.0(5.28), 8.1 and 8.2 before 8.2(5.35), 8.3 before 8.3(2.34), 8.4 before 8.4(4.11), 8.6 before 8.6(1.10), and 8.7 before 8.7(1.3), and Cisco Firewall Services Module (FWSM) software 3.1 and 3.2 before 3.2(24.1) and 4.0 and 4.1 before 4.1(11.1), allow remote attackers to cause a denial of service (device reload) via a crafted IKEv1 message, aka Bug IDs CSCub85692 and CSCud20267.

Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 7.0 through 7.2 before 7.2(5.7), 8.0 before 8.0(5.27), 8.1 before 8.1(2.53), 8.2 before 8.2(5.8), 8.3 before 8.3(2.25), 8.4 before 8.4(2.5), and 8.5 before 8.5(1.2) and the Firewall Services Module (FWSM) 3.1 and 3.2 before 3.2(23) and 4.0 and 4.1 before 4.1(8) in Cisco Catalyst 6500 series devices, when multicast routing is enabled, allow remote attackers to cause a denial of service (device reload) via a crafted IPv4 PIM message, aka Bug IDs CSCtr47517 and CSCtu97367.

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.0 before 7.0(8.11), 7.1 and 7.2 before 7.2(5.1), 8.0 before 8.0(5.19), 8.1 before 8.1(2.47), 8.2 before 8.2(2.19), and 8.3 before 8.3(1.8); Cisco PIX Security Appliances 500 series devices; and Cisco Firewall Services Module (aka FWSM) 3.1 before 3.1(20), 3.2 before 3.2(20), 4.0 before 4.0(15), and 4.1 before 4.1(5) allow remote attackers to cause a denial of service (device reload) via a malformed Skinny Client Control Protocol (SCCP) message, aka Bug IDs CSCtg69457 and CSCtl84952.

The Cisco Firewall Services Module (FWSM) 2.x, 3.1 before 3.1(16), 3.2 before 3.2(13), and 4.0 before 4.0(6) for Cisco Catalyst 6500 switches and Cisco 7600 routers allows remote attackers to cause a denial of service (traffic-handling outage) via a series of malformed ICMP messages.

Cisco PIX and ASA appliances with 7.0 through 8.0 software, and Cisco Firewall Services Module (FWSM) 3.1(5) and earlier, allow remote attackers to cause a denial of service (device reload) via a crafted MGCP packet, aka CSCsi90468 (appliance) and CSCsi00694 (FWSM).

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

Cisco Firewall Services Module (FWSM) in Cisco Catalyst 6500 and 7600 series devices allows remote attackers to cause a denial of service (crash and reload) via an SNMPv3 message when snmp-server is set.
