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

  - Mozilla developers and community members reported memory
    safety bugs present in Firefox 63 and Firefox ESR 60.3.
    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. This
    vulnerability affects Thunderbird < 60.4, Firefox ESR <
    60.4, and Firefox < 64. (CVE-2018-12405)

  - A use-after-free vulnerability can occur after deleting
    a selection element due to a weak reference to the
    select element in the options collection. This results
    in a potentially exploitable crash. This vulnerability
    affects Thunderbird < 60.4, Firefox ESR < 60.4, and
    Firefox < 64. (CVE-2018-18492)

  - A buffer overflow can occur in the Skia library during
    buffer offset calculations with hardware accelerated
    canvas 2D actions due to the use of 32-bit calculations
    instead of 64-bit. This results in a potentially
    exploitable crash. This vulnerability affects
    Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox <
    64. (CVE-2018-18493)

  - A same-origin policy violation allowing the theft of
    cross-origin URL entries when using the Javascript
    location property to cause a redirection to another site
    using performance.getEntries(). This is a same-origin
    policy violation and could allow for data theft. This
    vulnerability affects Thunderbird < 60.4, Firefox ESR <
    60.4, and Firefox < 64. (CVE-2018-18494)

  - A potential vulnerability leading to an integer overflow
    can occur during buffer size calculations for images
    when a raw value is used instead of the checked value.
    This leads to a possible out-of-bounds write. This
    vulnerability affects Thunderbird < 60.4, Firefox ESR <
    60.4, and Firefox < 64. (CVE-2018-18498)

  - Incorrect texture handling in Angle in Google Chrome
    prior to 70.0.3538.67 allowed a remote attacker to
    perform an out of bounds memory read via a crafted HTML
    page. (CVE-2018-17466)

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