FreeBSD : asterisk -- Outbound INVITE loop on challenge with different nonce (29b7f0be-1fb7-11eb-b9d4-001999f8d30b)

High Nessus Plugin ID 142535


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


The Asterisk project reports :

If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.


Update the affected packages.
