By establishing a large number of telnet sessions and forcing them to this state, an attacker can consume all available telnet sessions and prevent other users from establishing new telnet sessions.","impact":"This vulnerability allows a remote attacker to consume all available telnet sessions, resulting in a denial-of-service condition.","resolution":"Apply a patch from your vendor Microsoft has released a patch for this vulnerability; for further information, please consult the systems affected section below.","workarounds":"","sysaffected":"","thanks":"","author":"This document was written by Jeffrey P.
