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

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially
    exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a
    privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a
    cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability
    affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <
    78.1. (CVE-2020-15652)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR
    78.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some
    of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 79, Firefox
    ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

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