Cisco has patched a DoS vulnerability that affects multiple products.
According to Computerworld, the bug allows attackers to change the state of TCP connections, which would allow an attacker to force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough are forced into that state, acceptance of new TCP connections may be prevented, thereby initiating a DoS condition.
Affected products include a number of routers and switches running IOS, IOS-XE and CatOS operating systems; Cisco ASA and Cisco PIX security appliances; NX-OS-based products; and Scientific-Atlanta and Linksys products.
