         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.
