Description:
A vulnerability has been reported in Cisco IOS, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the connection handling and can be exploited via a specially crafted TCP connection to a telnet or reverse telnet port.
Successful exploitation blocks further access to management services using VTYs (virtual terminals) including telnet, reverse telnet, RSH, SSH, and in certain cases HTTP.
