"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2021:2264 advisory.

  - 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)

  - 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 this issue but has instead relied only on the application's self-reported version
number.");
