The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2874-1 advisory.

  - Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption     and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91,     Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29980)

  - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly     considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
    This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29984)

  - A use-after-free vulnerability in media channels could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29985)

  - A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable     crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.*     This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29986)

  - Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds     read or memory corruption, and a potentially exploitable crash. This vulnerability affects Thunderbird <     78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29988)

  - Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. 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 < 78.13, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29989)

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