Network World's Jim Duffy writes that Cisco has patched a software hole that could lead to a denial-of-service attack on routers and switches.

From the article:

The vulnerability allows attackers to manipulate the state of TCP connections, according to a Cisco security advisory released this week. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely.
