"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has pacemaker packages installed that are affected
by multiple vulnerabilities:

  - A flaw was found in the way pacemaker's client-server
    authentication was implemented in versions up to and
    including 2.0.0. A local attacker could use this flaw,
    and combine it with other IPC weaknesses, to achieve
    local privilege escalation. (CVE-2018-16877)

  - A use-after-free flaw was found in pacemaker up to and
    including version 2.0.1 which could result in certain
    sensitive information to be leaked via the system logs.
    (CVE-2019-3885)

  - A flaw was found in pacemaker up to and including
    version 2.0.1. An insufficient verification inflicted
    preference of uncontrolled processes can lead to DoS
    (CVE-2018-16878)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
