"The version of Firefox ESR installed on the remote macOS or Mac OS X
host is prior to 60.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the mfsa2019-02 advisory.

  - A use-after-free vulnerability can occur while parsing
    an HTML5 stream in concert with custom HTML elements.
    This results in the stream parser object being freed
    while still in use, leading to a potentially exploitable
    crash. (CVE-2018-18500)

  - An earlier fix for an Inter-process Communication (IPC)
    vulnerability, CVE-2011-3079, added authentication to
    communication between IPC endpoints and server parents
    during IPC process creation. This authentication is
    insufficient for channels created after the IPC process
    is started, leading to the authentication not being
    correctly applied to later channels. This could allow
    for a sandbox escape through IPC channels due to lack of
    message validation in the listener process.
    (CVE-2018-18505)

  - Mozilla developers and community members Alex Gaynor,
    Christoph Diehl, Steven Crane, Jason Kratzer, Gary
    Kwong, and Christian Holler reported memory safety bugs
    present in Firefox 64 and Firefox ESR 60.4. Some of
    these bugs showed evidence of memory corruption and we
    presume that with enough effort that some of these could
    be exploited to run arbitrary code. (CVE-2018-18501)

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