"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2021:1884-1 advisory.

  - The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network,
    grants normal remote users access to start or stop the service. This could be used to prevent the browser
    update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface
    in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10
    build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1,
    Firefox < 87, and Firefox ESR < 78.10.1. (CVE-2021-29951)

  - A locally-installed hostile program could send `WM_COPYDATA` messages that Firefox would process
    incorrectly, leading to an out-of-bounds read. *This bug only affects Firefox on Windows. Other operating
    systems are unaffected.*. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR <
    78.11. (CVE-2021-29964)

  - Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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 Thunderbird < 78.11, Firefox < 89, and
    Firefox ESR < 78.11. (CVE-2021-29967)

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