      asterisk: security bump to version 14.6.2 · 7776e245
      Peter Korsgaard authored
      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

      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.

      package/asterisk: fix host build · 52dfe8bf
      Yann E. MORIN authored
      
      
      The host menuselect tool is linked to our host libxml2 library, but it
      is missing an RPATH to the host directory.
      
      This is because menuselect does not use automake, so does not inherit
      the LDFLAGS from the configure run.
      
      We fix that by simply passing $(HOST_CONFIGURE_OPTS) in the make
      environment.
      
      At the same time, we also install the tool in the host directory, even
      if not used from there, so that the sanity checks we run are properly
      passed.
