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.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1854-1 advisory.

  - Thunderbird unprotects a secret OpenPGP key prior to using it for a decryption, signing or key import     task. If the task runs into a failure, the secret key may remain in memory in its unprotected state. This     vulnerability affects Thunderbird < 78.8.1. (CVE-2021-29950)

Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1,     Firefox < 87, and Firefox ESR < 78.10.1. (CVE-2021-29951)

  - OpenPGP secret keys that were imported using Thunderbird version 78.8.1 up to version 78.10.1 were stored     unencrypted on the user's local disk. The master password protection was inactive for those keys. Version     78.10.2 will restore the protection mechanism for newly imported keys, and will automatically protect keys     that had been imported using affected Thunderbird versions. This vulnerability affects Thunderbird <     78.10.2. (CVE-2021-29956)

  - If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an     additional unprotected part, Thunderbird did not indicate that only parts of the message are protected.
    This vulnerability affects Thunderbird < 78.10.2. (CVE-2021-29957)

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