Cisco IOS 12.0 through 15.6, Adaptive Security Appliance (ASA) Software 7.0.1 through 9.7.1.2, NX-OS 4.0 through 12.0, and IOS XE 3.6 through 3.18 are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated, remote attacker to take full control of the OSPF Autonomous System (AS) domain routing table, allowing the attacker to intercept or black-hole traffic. The attacker could exploit this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause the targeted router to flush its routing table and propagate the crafted OSPF LSA type 1 update throughout the OSPF AS domain. To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. This vulnerability can only be triggered by sending crafted unicast or multicast OSPF LSA type 1 packets. No other LSA type packets can trigger this vulnerability. OSPFv3 is not affected by this vulnerability. Fabric Shortest Path First (FSPF) protocol is not affected by this vulnerability. Cisco Bug IDs: CSCva74756, CSCve47393, CSCve47401.Show less

A vulnerability in the implementation of the H.264 protocol in Cisco Meeting Server (CMS) 2.1.4 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability exists because the affected application does not properly validate Fragmentation Unit (FU-A) protocol packets. An attacker could exploit this vulnerability by sending a crafted H.264 FU-A packet through the affected application. A successful exploit could allow the attacker to cause a DoS condition on the affected system due to an unexpected restart of the CMS media process on the system. Although the CMS platform continues to operate and only the single, affected CMS media process is restarted, a brief interruption of media traffic for certain users could occur.
