Rilasciati Asterisk 13.18.5, 14.7.5, 15.1.5 and 13.18-cert2 (Security)
The Asterisk Development Team would like to announce security releases for Asterisk 13, 14 and 15, and Certified Asterisk 13.18. The available releases are released as versions 13.18.5, 4.7.5, 15.1.5 and 13.18-cert2.
These releases are available for immediate download at
https://downloads.asterisk.org/pub/telephony/asterisk/releases
https://downloads.asterisk.org/pub/telephony/certified-asterisk/releases
The following security vulnerabilities were resolved in these versions:
* AST-2017-014: Crash in PJSIP resource when missing a contact header
A select set of SIP messages create a dialog in Asterisk. Those SIP messages
must contain a contact header. For those messages, if the header was not
present and using the PJSIP channel driver, it would cause Asterisk to crash.
The severity of this vulnerability is somewhat mitigated if authentication is
enabled. If authentication is enabled a user would have to first be authorized
before reaching the crash point.
For a full list of changes in the current releases, please see the ChangeLogs:

CVE Name
Description A select set of SIP messages create a dialog in Asterisk.
Those SIP messages must contain a contact header. For those
messages, if the header was not present and using the PJSIP
channel driver, it would cause Asterisk to crash. The
severity of this vulnerability is somewhat mitigated if
authentication is enabled. If authentication is enabled a
user would have to first be authorized before reaching the
crash point.
Resolution When using the Asterisk PJSIP resource, and one of the SIP
messages that create a dialog is received Asterisk now
checks to see if the message contains a contact header. If
it does not Asterisk now responds with a "400 Missing
Contact header".

AST-2017-012: Remote Crash Vulnerability in RTCP Stack
Asterisk Project Security Advisory - AST-2017-012
Product Asterisk
Summary Remote Crash Vulnerability in RTCP Stack
Nature of Advisory Denial of Service
Susceptibility Remote Unauthenticated Sessions
Severity Moderate
Exploits Known No
Reported On October 30, 2017
Reported By Tzafrir Cohen and Vitezslav Novy
Posted On December 13, 2017

CVE Name
Description If a compound RTCP packet is received containing more than
one report (for example a Receiver Report and a Sender
Report) the RTCP stack will incorrectly store report
information outside of allocated memory potentially causing
a crash.
For all versions of Asterisk this vulnerability requires an
active call to be established.
For versions of Asterisk 13.17.2, 14.6.2, 15.0.0,
13.13-cert6 and greater an additional level of security is
placed upon RTCP packets. If the probation period for
incoming RTP traffic has passed any received RTCP packets
must contain the same SSRC as the RTP traffic. If the RTCP
packets do not then they are dropped. This ensures other
parties can not inject RTCP packets without they themselves
establishing an active call.
Resolution The RTCP stack has been changed so the report information is
always stored in allocated memory. The provided patches can
be applied to the appropriate version or the latest version
of Asterisk can be installed to receive the fix.
