-Subject: [PATCH] Curl_sasl_create_digest_md5_message: fix buffer overflow
-
-When negotiating SASL DIGEST-MD5 authentication, the function
-Curl_sasl_create_digest_md5_message() uses the data provided from the
-server without doing the proper length checks and that data is then
-appended to a local fixed-size buffer on the stack.
-
-This vulnerability can be exploited by someone who is in control of a
-server that a libcurl based program is accessing with POP3, SMTP or
-IMAP. For applications that accept user provided URLs, it is also
-thinkable that a malicious user would feed an application with a URL to
-a server hosting code targetting this flaw.
-
-Bug: http://curl.haxx.se/docs/adv_20130206.html
-
-[upstream commit f206d6c055d1008f0edb6d5d5920f0f300b9983a]
