+Subject: [PATCH] Determine appropriate salt for invalid users.
+
+When sshd is processing a non-PAM login for a non-existent user it uses
+the string from the fakepw structure as the salt for crypt(3)ing the
+password supplied by the client.  That string has a Blowfish prefix, so on
+systems that don't understand that crypt will fail fast due to an invalid
+salt, and even on those that do it may have significantly different timing
+from the hash methods used for real accounts (eg sha512).  This allows
+user enumeration by, eg, sending large password strings.  This was noted
+by EddieEzra.Harari at verint.com (CVE-2016-6210).
+
+To mitigate, use the same hash algorithm that root uses for hashing
+passwords for users that do not exist on the system.  ok djm@

+Subject: [PATCH] Mitigate timing of disallowed users PAM logins.
+
+When sshd decides to not allow a login (eg PermitRootLogin=no) and
+it's using PAM, it sends a fake password to PAM so that the timing for
+the failure is not noticeably different whether or not the password
+is correct.  This behaviour can be detected by sending a very long
+password string which is slower to hash than the fake password.
+
+Mitigate by constructing an invalid password that is the same length
+as the one from the client and thus takes the same time to hash.

-Author: Jakub Jelen <jjelen@redhat.com>

-Created as a response to rhbz#1251777 and previous one rhbz#1225106.
-The code of pam module is outdated and compiled with current openssh
-version which went through quite enough refactoring.
