The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1582-1 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)

  - An issue present in lowering/register allocation could have led to obscure but deterministic register     confusion failures in JITted code that would lead to a potentially exploitable crash. This vulnerability     affects Firefox < 91 and Thunderbird < 91. (CVE-2021-29981)

  - Due to incorrect JIT optimization, we incorrectly interpreted data from the wrong type of object,     resulting in the potential leak of a single bit of memory. This vulnerability affects Firefox < 91 and     Thunderbird < 91. (CVE-2021-29982)

  - Firefox for Android could get stuck in fullscreen mode and not exit it even after normal interactions that     should cause it to exit. *Note: This issue only affected Firefox for Android. Other operating systems are     unaffected.*. This vulnerability affects Firefox < 91. (CVE-2021-29983)

  - 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)

  - After requesting multiple permissions, and closing the first permission panel, subsequent permission     panels will be displayed in a different position but still record a click in the default location, making     it possible to trick a user into accepting a permission they did not want to. *This bug only affects     Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and     Thunderbird < 91. (CVE-2021-29987)

  - 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)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 90. 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 < 91. (CVE-2021-29990)

  - Firefox incorrectly accepted a newline in a HTTP/3 header, interpretting it as two separate headers. This     allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox <     91.0.1 and Thunderbird < 91.0.1. (CVE-2021-29991)

  - When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might     allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug     only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects     Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1.
    (CVE-2021-38492)

  - Mozilla developers reported memory safety bugs present in Thunderbird 78.13.0. 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 Thunderbird < 91.1 and Firefox ESR < 91.1.
    (CVE-2021-38495)

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