From the Bugtraq vulnerabilities:
"Cisco IOS telnet service is reported prone to a remote denial of service vulnerability. It is reported that an attacker can trigger this issue by sending a specially crafted TCP packet to a telnet or reverse telnet port of a Cisco device running IOS.
All Cisco devices running IOS with a telnet or reverse telnet service are affected by this issue. "
The article is here: http://www.securityfocus.com/bid/11060/info/
It says there aren't any known exploits yet. I wonder if this means denial of service to the telnet daemon running in IOS, or the actual device itself !?
