# SECURITY FIXES
* for CVE-2012-3482:
NTLM: fetchmail mistook an error message that the server sent in response to
an NTLM request for protocol exchange, tried to decode it, and crashed while
reading from a bad memory location.
Also, with a carefully crafted NTLM challenge packet sent from the server, it
would be possible that fetchmail conveyed confidential data not meant for the
server through the NTLM response packet.
Fix: Detect base64 decoding errors, validate the NTLM challenge, and abort
NTLM authentication in case of error.
See fetchmail-SA-2012-02.txt for further details.
Reported by J. Porter Clark.
* for CVE-2011-3389:
SSL/TLS (wrapped and STARTTLS): fetchmail used to disable a countermeasure
against a certain kind of attack against cipher block chaining initialization
vectors (SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS).
Whether this creates an exploitable situation, depends on the server and the
negotiated ciphers.
As a precaution, fetchmail 6.3.22 enables the countermeasure, by clearing
SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.
NOTE that this can cause connections to certain non-conforming servers to
fail, in which case you can set the environment variable
FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE to any non-empty value when starting
fetchmail to re-instate the compatibility option at the expense of security.
Reported by Apple Product Security.

# BUG FIX
* The Server certificate: message in verbose mode now appears on stdout like the
remainder of the output. Reported by Henry Jensen, to fix Debian Bug #639807.
* The GSSAPI-related autoconf code now matches gssapi.c better, and uses
a different check to look for GSS_C_NT_HOSTBASED_SERVICE.
This fixes the GSSAPI-enabled build on NetBSD 6 Beta.
# CHANGES
* On systems where SSLv2_client_method isn't defined in OpenSSL (such as
newer Debian, and Ubuntu starting with 11.10 oneiric ocelot), don't
reference it (to fix the build) and if configured, print a run-time error
that the OS does not support SSLv2. Fixes Debian Bug #622054,
but note that that bug report has a more thorough patch that does away with
SSLv2 altogether.
* The security and errata notices fetchmail-{EN,SA}-20??-??.txt are now
under the more relaxed CC BY-ND 3.0 license (the noncommercial clause
was dropped). The Creative Commons address was updated.
* The Python-related Makefile.am parts were simplified to avoid an automake
1.11.X bug around noinst_PYTHON, Automake Bug #10995.
* Configuring fetchmail without SSL now triggers a configure warning,
and asks the user to consider running configure --with-ssl.
# WORKAROUNDS
* Some servers, notably Zimbra, return A1234 987 FETCH () in response to
a header request, in the face of message corruption. fetchmail now treats
these as temporary errors. Report and Patch by Mikulas Patocka, Red Hat.
* Some servers, notably Microsoft Exchange, return "A0009 OK FETCH completed."
without any header in response to a header request for meeting reminder
messages (with a "meeting.ics" attachment). fetchmail now treats these as
transient errors. Report by John Connett, Patch by Sunil Shetye.

- Security fixes for CVE-2009-2666, CVE-2007-4565 and CVE-2008-2711.
- Fetchmail no longer drops permanently undelivered messages by default,
to match historic documentation. It does this by adding a new
"softbounce" option.
- A lot bug fixes and improvements.
The list of changes since version 6.2.5.5 is too large to mention here.
The new version provides a fix for the vulnerability reported in the
fetchmail-SA-2006-02.txt advisory.
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.
And always is defined as share/examples/rc.d
which was the default before.
This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.
This was discussed on tech-pkg in late January and late April.
Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.
the RCD_SCRIPTS rc.d script(s) to the PLIST.
This GENERATE_PLIST idea is part of Greg A. Woods'
PR #22954.
This helps when the RC_SCRIPTS are installed to
a different ${RCD_SCRIPTS_EXAMPLEDIR}. (Later,
the default RCD_SCRIPTS_EXAMPLEDIR will be changed
to be more clear that they are the examples.)
These patches also remove the etc/rc.d/ scripts from PLISTs
(of packages that use RCD_SCRIPTS). (This also removes
now unused references from openssh* makefiles. Note that
qmail package has not been changed yet.)
I have been doing automatic PLIST registration for RC_SCRIPTS
for over a year. Not all of these packages have been tested,
but many have been tested and used.
Somethings maybe to do:
- a few packages still manually install the rc.d scripts to
hard-coded etc/rc.d. These need to be fixed.
- maybe remove from mk/${OPSYS}.pkg.dist mtree specifications too.
