Description Tomas Hoger 2009-02-27 08:59:18 EST
It was discovered that camel's NTLM SASL authentication mechanism did not properly validate server's challenge packets (NTLM authentication type 2 packets, ). In the ntlm_challenge() in camel/camel-sasl-ntlm.c, length of the domain string that was copied from type 2 to type 3 packet (client's reply to server's challenge) was not properly validated against the rest of the data received from the server. 127 ntlm_set_string (ret, NTLM_RESPONSE_DOMAIN_OFFSET, 128 token->data + NTLM_CHALLENGE_DOMAIN_OFFSET, 129 atoi (token->data + NTLM_CHALLENGE_DOMAIN_LEN_OFFSET)); Server could specify larger length than the actual data sent in the packet, causing the client to disclose portion of its memory, or crash. Note: length value was not properly extracted from the packet too, as it is not passed as string, rather as 16-bit LE value.  http://curl.haxx.se/rfc/ntlm.html#theType2Message

Comment 28 Milan Crha 2009-05-19 07:22:18 EDT
See bug #501222, the NTLM authentication in IMAP seems to be broken. I'm checking with a reporter there, but want to let you know soon enough.
Comment 29 Sergey Panov 2009-06-13 02:02:02 EDT
I am using 4 different Fedora 10 machines. When this bug fix was pushed through Fedora 10 update (evolution-data-server-2.24.5-4.fc10) it killed (one-by-one) password authentication with the SMTP server. The SMTP server is a Windows 2003 server running Exchange. Password type is set to NTLM/SPA . All machines are have evolution-data-server-2.24.5-5.fc10 installed. SMTP problem is still there. At least one of the systems developed problem similar to one described in Comment #29 -- it fails to authenticate with the real(evolution exchange module) exchange server.
