FreeBSD : asterisk -- Unauthorized data disclosure and shell access command injection in app_minivm (c599f95c-8ee5-11e7-8be8-001999f8d30b)

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

The Asterisk project reports :

AST-2017-005 - 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.

AST-2017-006 - 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.
