The release of Asterisk 10.1.0 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:
* AST-2012-001: prevent crash when an SDP offer
is received with an encrypted video stream when support for video
is disabled and res_srtp is loaded. (closes issue ASTERISK-19202)
Reported by: Catalin Sanda
* Allow playback of formats that don't support seeking. ast_streamfile
previously did unconditional seeking on files that broke playback of
formats that don't support that functionality. This patch avoids the
seek that was causing the problem.
(closes issue ASTERISK-18994) Patched by: Timo Teras
* Add pjmedia probation concepts to res_rtp_asterisk's learning mode. In
order to better handle RTP sources with strictrtp enabled (which is the
default setting in 10) using the learning mode to figure out new sources
when they change is handled by checking for a number of consecutive (by
sequence number) packets received to an rtp struct based on a new
configurable value called 'probation'. Also, during learning mode instead
of liberally accepting all packets received, we now reject packets until a
clear source has been determined.
* Handle AST_CONTROL_UPDATE_RTP_PEER frames in local bridge loop. Failing
to handle AST_CONTROL_UPDATE_RTP_PEER frames in the local bridge loop
causes the loop to exit prematurely. This causes a variety of negative side
effects, depending on when the loop exits. This patch handles the frame by
essentially swallowing the frame in the local loop, as the current channel
drivers expect the RTP bridge to handle the frame, and, in the case of the
local bridge loop, no additional action is necessary.
(closes issue ASTERISK-19095) Reported by: Stefan Schmidt Tested
by: Matt Jordan
* Fix timing source dependency issues with MOH. Prior to this patch,
res_musiconhold existed at the same module priority level as the timing
sources that it depends on. This would cause a problem when music on
hold was reloaded, as the timing source could be changed after
res_musiconhold was processed. This patch adds a new module priority
level, AST_MODPRI_TIMING, that the various timing modules are now loaded
at. This now occurs before loading other resource modules, such
that the timing source is guaranteed to be set prior to resolving
the timing source dependencies.
(closes issue ASTERISK-17474) Reporter: Luke H Tested by: Luke H,
Vladimir Mikhelson, zzsurf, Wes Van Tlghem, elguero, Thomas Arimont
Patched by elguero
* Fix RTP reference leak. If a blind transfer were initiated using a
REFER without a prior reINVITE to place the call on hold, AND if Asterisk
were sending RTCP reports, then there was a reference leak for the
RTP instance of the transferrer.
(closes issue ASTERISK-19192) Reported by: Tyuta Vitali
* Fix blind transfers from failing if an 'h' extension
is present. This prevents the 'h' extension from being run on the
transferee channel when it is transferred via a native transfer
mechanism such as SIP REFER. (closes issue ASTERISK-19173) Reported
by: Ross Beer Tested by: Kristjan Vrban Patches: ASTERISK-19173 by
Mark Michelson (license 5049)
* Restore call progress code for analog ports. Extracting sig_analog
from chan_dahdi lost call progress detection functionality. Fix
analog ports from considering a call answered immediately after
dialing has completed if the callprogress option is enabled.
(closes issue ASTERISK-18841)
Reported by: Richard Miller Patched by Richard Miller
* Fix regression that 'rtp/rtcp set debup ip' only works when a port
was also specified.

Asterisk Project Security Advisory - AST-2012-001
Copyright (c) 2012 Digium, Inc. All Rights Reserved.
Permission is hereby granted to distribute and publish this advisory in its
original, unaltered form.
The Asterisk Development Team is proud to announce the release of
Asterisk 10.0.0. This release is available for immediate download
at http://downloads.asterisk.org/pub/telephony/asterisk/
Asterisk 10 is the next major release series of Asterisk. It will
be a Standard support release, similar to Asterisk 1.6.2. For more
information about support time lines for Asterisk releases, see
the Asterisk versions page:
https://wiki.asterisk.org/wiki/display/AST/Asterisk+Versions
With the release of the Asterisk 10 branch, the preceding '1.' has
been removed from the version number per the blog post available
at
http://blogs.digium.com/2011/07/21/the-evolution-of-asterisk-or-how-we-arrived-at-asterisk-10/
The release of Asterisk 10 would not have been possible without
the support and contributions of the community.
You can find an overview of the work involved with the 10.0.0
release in the summary:
http://svn.asterisk.org/svn/asterisk/tags/10.0.0/asterisk-10.0.0-summary.txt
A short list of available features includes:
* T.38 gateway functionality has been added to res_fax.
* Protocol independent out-of-call messaging support. Text messages not
associated with an active call can now be routed through the Asterisk
dialplan. SIP and XMPP are supported so far.
* New highly optimized and customizable ConfBridge application capable
of mixing audio at sample rates ranging from 8kHz-192kHz
* Addition of video_mode option in confbridge.conf to provide basic video
conferencing in the ConfBridge() dialplan application.
* Support for defining hints has been added to pbx_lua.
* Replacement of Berkeley DB with SQLite for the Asterisk Database (AstDB).
* Much, much more!
A full list of new features can be found in the CHANGES file.
http://svn.asterisk.org/svn/asterisk/branches/10/CHANGES
Also, when upgrading a system between major versions, it is imperative
that you read and understand the contents of the UPGRADE.txt file,
which is located at:
http://svn.asterisk.org/svn/asterisk/branches/10/UPGRADE.txt
Thank you for your continued support of Asterisk!
share/doc/asterisk/AST.{txt,pdf} has been replaced with
share/doc/asterisk/Asterisk_Admin_Guide. You will need a browser
to read the latter.
----- Asterisk 1.8.8.1 -----
The release of Asterisk 1.8.8.1 resolves a regression introduced
in Asterisk 1.8.8.0 reported by the community, and would have not
been possible without your participation. Thank you!
The following is the issue resolved in this release:
* Handle AST_CONTROL_UPDATE_RTP_PEER frames in local bridge loop
Failing to handle AST_CONTROL_UPDATE_RTP_PEER frames in the local
bridge loop causes the loop to exit prematurely. This causes a
variety of negative side effects, which may include having Music
On Hold failing during a SIP Hold.
For a full description of the changes in this release, please see the ChangeLog:
http://downloads.asterisk.org/pub/telephony/asterisk/ChangeLog-1.8.8.1
Thank you for your continued support of Asterisk!
----- Asterisk 1.8.8.0 -----
The release of Asterisk 1.8.8.0 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:
* Updated SIP 484 handling; added Incomplete control frame
When a SIP phone uses the dial application and receives a 484
Address Incomplete response, if overlapped dialing is enabled
for SIP, then the 484 Address Incomplete is forwarded back to
the SIP phone and the HANGUPCAUSE channel variable is set to
28. Previously, the Incomplete application dialplan logic was
automatically triggered; now, explicit dialplan usage of the
application is required.
* Prevent IAX2 from getting IPv6 addresses via DNS
IAX2 does not support IPv6 and getting such addresses from DNS
can cause error messages on the remote end involving bad IPv4
address casts in the presence of IPv6/IPv4 tunnels.
* Fix bad RTP media bridges in directmedia calls on peers separated by
multiple Asterisk nodes.
* Fix crashes in ast_rtcp_write()
* Fix for incorrect voicemail duration in external notifications.
This patch fixes an issue where the voicemail duration was being
reported with a duration significantly less than the actual
sound file duration.
* Prevent segfault if call arrives before Asterisk is fully booted.
* Fix remote Crash Vulnerability in SIP channel driver (AST-2011-012)
http://downloads.asterisk.org/pub/security/AST-2011-012.pdf
* Fix locking order in app_queue.c which caused deadlocks
* Fix regression in configure script for libpri capability checks
* Prevent BLF subscriptions from causing deadlocks.
* Fix deadlock if peer is destroyed while sending MWI notice.
* Fix issue with setting defaultenabled on categories that are already
enabled by default.
* Don't crash on INFO automon request with no channel
AST-2011-014. When automon was enabled in features.conf, it
was possible to crash Asterisk by sending an INFO request if
no channel had been created yet.
* Fixed crash from orphaned MWI subscriptions in chan_sip
This patch resolves the issue where MWI subscriptions are orphaned
by subsequent SIP SUBSCRIBE messages.
* Default to nat=yes; warn when nat in general and peer differ
AST-2011-013. 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.
For a full list of changes in this release, please see the ChangeLog:
http://downloads.asterisk.org/pub/telephony/asterisk/ChangeLog-1.8.8.0
Thank you for your continued support of Asterisk!
The release of Asterisk 1.6.2.22 corrects two flaws in sip.conf.sample
related to AST-2011-013:
* The sample file listed *two* values for the 'nat' option as being the default.
Only 'yes' is the default.
* The warning about having differing 'nat' settings confusingly referred to both
peers and users.
For a full list of changes in this release, please see the ChangeLog:

Summary Possible remote enumeration of SIP endpoints with

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.

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.

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.
