CVE Name
Description It is possible to enumerate SIP usernames when the general
and user/peer NAT settings differ in whether to respond to
the port a request is sent from or the port listed for
responses in the Via header. In 1.4 and 1.6.2, this would
mean if one setting was nat=yes or nat=route and the other
was either nat=no or nat=never. In 1.8 and 10, this would
mean when one was nat=force_rport or nat=yes and the other
was nat=no or nat=comedia.
Resolution Handling NAT for SIP over UDP requires the differing
behavior introduced by these options.
To lessen the frequency of unintended username disclosure,
the default NAT setting was changed to always respond to the
port from which we received the request-the most commonly
used option.
Warnings were added on startup to inform administrators of
the risks of having a SIP peer configured with a different
setting than that of the general setting. The documentation
now strongly suggests that peers are no longer configured
for NAT individually, but through the global setting in the
"general" context.
Affected Versions
Product Release Series
Asterisk Open Source All All versions
Corrected In
As this is more of an issue with SIP over UDP in general, there is no
fix supplied other than documentation on how to avoid the problem. The
default NAT setting has been changed to what we believe the most
commonly used setting for the respective version in Asterisk 1.4.43,
1.6.2.21, and 1.8.7.2.

CVE Name
Description When the "automon" feature is enabled in features.conf, it
is possible to send a sequence of SIP requests that cause
Asterisk to dereference a NULL pointer and crash.
Resolution Applying the referenced patches that check that the pointer
is not NULL before accessing it will resolve the issue. The
"automon" feature can be disabled in features.conf as a
workaround.

This update adds a "jabber" option which is enabled by default.
This option pulls in iksemel which is used by the res_jabber.
Doing this allows chan_jingle (jabber) and chan_gtalk to work.

1.8.7.0:
========
The release of Asterisk 1.8.7.0 resolves several issues reported
by the community and would have not been possible without your
participation. Thank you!
Please note that a significant numbers of changes and fixes have
gone into features.c in this release (call parking, built-in
transfers, call pickup, etc.).
NOTE:
Recently, we were notified that the mechanism included in our
Asterisk source code releases to download and build support for
the iLBC codec had stopped working correctly; a little investigation
revealed that this occurred because of some changes on the
ilbcfreeware.org website. These changes occurred as a result of
Google's acquisition of GIPS, who produced (and provided licenses
for) the iLBC codec.
If you are a user of Asterisk and iLBC together, and you've already
executed a license agreement with GIPS, we believe you can continue
using iLBC with Asterisk. If you are a user of Asterisk and iLBC
together, but you had not executed a license agreement with GIPS,
we encourage you to research the situation and consult with your
own legal representatives to determine what actions you may want
to take (or avoid taking).
More information is available on the Asterisk blog:
http://blogs.asterisk.org/2011/09/19/ilbc-support-in-asterisk-after-googles-acquisition-of-gips/
The following is a sample of the issues resolved in this release:
* Added the 'storesipcause' option to sip.conf to allow the user to
disable the setting of HASH(SIP_CAUSE,) on the channel. Having
chan_sip set HASH(SIP_CAUSE,) on the channel carries a significant
performance penalty because of the usage of the MASTER_CHANNEL()
dialplan function.
We've decided to disable this feature by default in future 1.8
versions. This would be an unexpected behavior change for anyone
depending on that SIP_CAUSE update in their dialplan. Please
refer to the asterisk-dev mailing list more information:
http://lists.digium.com/pipermail/asterisk-dev/2011-August/050626.html
* Significant fixes and improvements to parking lots.
(Closes issues ASTERISK-17183, ASTERISK-17870, ASTERISK-17430,
ASTERISK-17452, ASTERISK-17452, ASTERISK-15792.)
* Numerous issues have been reported for deadlocks that are caused
by a blocking read in res_timing_timerfd on a file descriptor
that will never be written to.
A change to Asterisk adds some checks to make sure that the
timerfd is both valid and armed before calling read(). Should
fix: ASTERISK-18142, ASTERISK-18197, ASTERISK-18166 and possibly
others. (In essence, this change should make res_timing_timerfd
usable.)
* Resolve segfault when publishing device states via XMPP and not connected.
(Closes issue ASTERISK-18078.)
* Refresh peer address if DNS unavailable at peer creation.
(Closes issue ASTERISK-18000)
* Fix the missing DAHDI channels when using the newer chan_dahdi.conf
sections for channel configuration.
(Closes issue ASTERISK-18496.)
* Remove unnecessary libpri dependency checks in the configure script.
(Closes issue ASTERISK-18535.)
* Update get_ilbc_source.sh script to work again.
(Closes issue ASTERISK-18412)
For a full list of changes in this release, please see the ChangeLog:

Thank you for your continued support of Asterisk!
1.8.6.0:
========
The release of Asterisk 1.8.6.0 resolves several issues reported
by the community and would have not been possible without your
participation. Thank you!
The following is a sample of the issues resolved in this release:
* Fix an issue with Music on Hold classes losing files in playlist
when realtime is used. (Closes issue ASTERISK-17875.)
* Resolve a potential crash in chan_sip when utilizing auth= and
performing a 'sip reload' from the console. (Closes issue
ASTERISK-17939.)
* Address some improper sql statements in res_odbc that would cause
an update to fail on realtime peers due to trying to set as
"(NULL)" rather than an actual NULL. (Closes issue ASTERISK-17791.)
* Resolve issue where 403 Forbidden would always be sent maximum
number of times regardless to receipt of ACK.
* Resolve issue where if a call to MeetMe includes both the dynamic(D)
and always request PIN(P) options, MeetMe will ask for the PIN
two times: once for creating the conference and once for entering
the conference.
* Fix New Zealand indications profile based on
http://www.telepermit.co.nz/TNA102.pdf
(Closes issue ASTERISK-16263.)
* Segfault in shell_helper in func_shell.c
(Closes issue ASTERISK-18109.)

Thank you for your continued support of Asterisk!

The bug was introduced with the "assume_registered" option.
- Fixed RT #57585. Thanks to Eric Kössldorfer for his patch and
test case.
