Comment 17 for bug 1036509

A denial of service flaw was found in the way Fetchmail, a remote mail retrieval and forwarding utility, performed base64 decoding of certain NTLM server responses. Upon sending the NTLM authentication request, Fetchmail did not check if the received response was actually part of NTLM protocol exchange, or server-side error message and session abort. A rogue NTML server could use this flaw to cause fetchmail executable crash.
