"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2021:2883 advisory.

  - If Thunderbird was configured to use STARTTLS for an IMAP connection, and an attacker injected IMAP server
    responses prior to the completion of the STARTTLS handshake, then Thunderbird didn't ignore the injected
    data. This could have resulted in Thunderbird showing incorrect information, for example the attacker
    could have tricked Thunderbird to show folders that didn't exist on the IMAP server. This vulnerability
    affects Thunderbird < 78.12. (CVE-2021-29969)

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