Subject: SASL 2.1.27 rc5
All,
I have built a fourth release candidate of SASL 2.1.27 which can
be downloaded from here:

Note that the distro has been signed by my colleague Partha Susarla
at FastMail.
The only major change since RC4 has to do with detection of PAM
support. Those using PAM with saslauthd are encouraged to make sure
that this release compiles and runs as expected.
The (mostly) complete list of changes from 2.1.26 are these:
Added support for OpenSSL 1.1
Added support for lmdb (from Howard Chu)
Lots of build fixes (from Ignacio Casal Quinteiro and others)
Treat SCRAM and DIGEST-MD5 as more secure than PLAIN when
selecting client mech
DIGEST-MD5 plugin:
Fixed memory leaks
Fixed a segfault when looking for non-existent reauth
cache
Prevent client from going from step 3 back to step 2
Allow cmusaslsecretDIGEST-MD5 property to be disabled
GSSAPI plugin:
Added support for retrieving negotiated SSF
Fixed GSS-SPNEGO to use flags negotiated by GSSAPI for SSF
Properly compute maxbufsize AFTER security layers have
been set
SCRAM plugin:
Added support for SCRAM-SHA-256
LOGIN plugin:
Don’t prompt client for password until requested by server
NTLM plugin:
Fixed crash due to uninitialized HMAC context
saslauthd:
cache.c:
Don’t use cached credentials if timeout has expired
Fixed debug logging output
ipc_doors.c:
Fixed potential DoS attack (from Oracle)
ipc_unix.c:
Prevent premature closing of socket
auth_rimap.c:
Added support LOGOUT command
Added support for unsolicited CAPABILITY responses in
LOGIN reply
Properly detect end of responses (don’t needlessly
wait)
Properly handle backslash in passwords
auth_httpform:
Fix off-by-one error in string termination
Added support for 204 success response
auth_krb5.c:
Added krb5_conv_krb4_instance option
Added more verbose error logging
At this point any major changes (e.g. API, wire protocol) will be
pushed out to 2.1.28 or 2.2.0. I believe that this is close to
being a final release which I would like to get out by the end of
September.
The biggest outstanding issues are those around recent GSSAPI
changes. I'm inclined to defer to Alexey's judgement on these
unless someone can convince us that the SASL code is wrong per the
specs. The fact that it broke a particular piece of code doesn't
necessarily mean that the application code is correct and the SASL
change was wrong.
If there are any other last minute show stoppers, please open an
issue on GitHub (preferably with a patch), or better yet create a
pull request.
