"The version of Nessus Agent installed on the remote host is
6.10.x prior to 6.10.5. It is, therefore, affected by the following
vulnerabilities :

  - A denial of service vulnerability exists in the agent
    mode functionality due to insecure permissions. An
    authenticated, remote attacker can exploit this, via a
    specially crafted sequence of events, to prevent the
    agent from conducting scans. (CVE-2017-7849)

  - A local privilege escalation vulnerability exists in the
    agent mode functionality due to insecure permissions. A
    local attacker can exploit this, via a specially crafted
    sequence of events, to gain elevated privileges.
