The OSPF implementation in Cisco IOS 12.0 through 12.4 and 15.0 through 15.3, IOS-XE 2.x through 3.9.xS, ASA and PIX 7.x through 9.1, FWSM, NX-OS, and StarOS before 14.0.50488 does not properly validate Link State Advertisement (LSA) type 1 packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a (1) unicast or (2) multicast packet, aka Bug IDs CSCug34485, CSCug34469, CSCug39762, CSCug63304, and CSCug39795.

Unspecified vulnerability in Cisco PIX 500 Series Security Appliance and 5500 Series Adaptive Security Appliance (ASA) before 7.2(3)6 and 8.0(3), when the Time-to-Live (TTL) decrement feature is enabled, allows remote attackers to cause a denial of service (device reload) via a crafted IP packet.

Cisco PIX 500 and ASA 5500 Series Security Appliances 6.x before 6.3(5.115), 7.0 before 7.0(5.2), and 7.1 before 7.1(2.5), and the FWSM 3.x before 3.1(3.24), when the "inspect sip" option is enabled, allows remote attackers to cause a denial of service (device reboot) via malformed SIP packets.

Cisco PIX 500 and ASA 5500 Series Security Appliances 7.0 before 7.0(4.14) and 7.1 before 7.1(2.1), and the FWSM 2.x before 2.3(4.12) and 3.x before 3.1(3.24), when "inspect http" is enabled, allows remote attackers to cause a denial of service (device reboot) via malformed HTTP traffic.
