Fixes the following security issues:
14.6.1:
* AST-2017-005 (applied to all released versions): The "strictrtp" option in
rtp.conf enables a feature of the RTP stack that learns the source address
of media for a session and drops any packets that do not originate from
the expected address. This option is enabled by default in Asterisk 11
and above. The "nat" and "rtp_symmetric" options for chan_sip and
chan_pjsip respectively enable symmetric RTP support in the RTP stack.
This uses the source address of incoming media as the target address of
any sent media. This option is not enabled by default but is commonly
enabled to handle devices behind NAT.
A change was made to the strict RTP support in the RTP stack to better
tolerate late media when a reinvite occurs. When combined with the
symmetric RTP support this introduced an avenue where media could be
hijacked. Instead of only learning a new address when expected the new
code allowed a new source address to be learned at all times.
If a flood of RTP traffic was received the strict RTPsupport would allow
the new address to provide media and with symmetric RTP enabled outgoing
traffic would be sent to this new address, allowing the media to be
hijacked. Provided the attacker continued to send traffic they would
continue to receive traffic as well.
* AST-2017-006 (applied to all released versions): The app_minivm module has
an “externnotify” program configuration option that is executed by the
MinivmNotify dialplan application. The application uses the caller-id
name and number as part of a built string passed to the OS shell for
interpretation and execution. Since the caller-id name and number can
come from an untrusted source, a crafted caller-id name or number allows
an arbitrary shell command injection.
* AST-2017-007 (applied only to 13.17.1 and 14.6.1): A carefully crafted URI
in a From, To or Contact header could cause Asterisk to crash

https://www.asterisk.org/downloads/asterisk-news/asterisk-11252-13171-1461-116-cert17-1313-cert5-now-available-security
14.6.2:
* AST-2017-008: Insufficient RTCP packet validation could allow reading
stale buffer contents and when combined with the “nat” and “symmetric_rtp”
options allow redirecting where Asterisk sends the next RTCP report.
The RTP stream qualification to learn the source address of media always
accepted the first RTP packet as the new source and allowed what
AST-2017-005 was mitigating. The intent was to qualify a series of
packets before accepting the new source address.

Drop 0004-configure-in-cross-complation-assimne-eventfd-are-av.patch as this
is now handled differently upstream (by disabling eventfd for cross
compilation, see commit
2e927990b3d2 (eventfd: Disable during cross
compilation)). If eventfd support is needed then this should be submitted
upstream.

-Assume that no one building from now on for cross-compilation will be
-unlucky enough to get versions older than that...

-As such, in cross-compilation, assume eventfd are available.
