Cisco Security Advisory - Cisco IOS Software contains a denial of service (DoS) vulnerability in the Wide Area Application Services (WAAS) Express feature that could allow an unauthenticated, remote attacker to cause the router to leak memory or to reload. Cisco IOS Software also contains a DoS vulnerability in the Measurement, Aggregation, and Correlation Engine (MACE) feature that could allow an unauthenticated, remote attacker to cause the router to reload. An attacker could exploit these vulnerabilities by sending transit traffic through a router configured with WAAS Express or MACE. Successful exploitation of these vulnerabilities could allow an unauthenticated, remote attacker to cause the router to leak memory or to reload. Repeated exploits could allow a sustained DoS condition. Cisco has released free software updates that address these vulnerabilities.

Cisco Security Advisory - Cisco IOS Software Release, 15.1(2)T is affected by a denial of service (DoS) vulnerability during the TCP establishment phase. The vulnerability could cause embryonic TCP connections to remain in a SYNRCVD or SYNSENT state. Enough embryonic TCP connections in these states could consume system resources and prevent an affected device from accepting or initiating new TCP connections, including any TCP-based remote management access to the device. No authentication is required to exploit this vulnerability. An attacker does not need to complete a three-way handshake to trigger this vulnerability; therefore, this this vulnerability can be exploited using spoofed packets. This vulnerability may be triggered by normal network traffic.
