Asterisk project reports :

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.

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.


Update the affected packages.
