There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in manager.c in Sangoma Asterisk through 13.x, 16.x, 17.x and Certified Asterisk
    13.21 through 13.21-cert4. A remote authenticated Asterisk Manager Interface (AMI) user without system
    authorization could use a specially crafted Originate AMI request to execute arbitrary system commands.
    (CVE-2019-18610)

  - An issue was discovered in channels/chan_sip.c in Sangoma Asterisk 13.x before 13.29.2, 16.x before
    16.6.2, and 17.x before 17.0.1, and Certified Asterisk 13.21 before cert5. A SIP request can be sent to
    Asterisk that can change a SIP peer's IP address. A REGISTER does not need to occur, and calls can be
    hijacked as a result. The only thing that needs to be known is the peer's name; authentication details
    such as passwords do not need to be known. This vulnerability is only exploitable when the nat option is
    set to the default, or auto_force_rport. (CVE-2019-18790)
