"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2021:2458-1 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)

  - A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially
    exploitable crash. *This bug could only be triggered when accessibility was enabled.*. This vulnerability
    affects Thunderbird < 78.12, Firefox ESR < 78.12, and Firefox < 90. (CVE-2021-29970)

  - Mozilla developers reported memory safety bugs present in code shared between Firefox and Thunderbird.
    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 < 78.12,
    Firefox ESR < 78.12, and Firefox < 90. (CVE-2021-29976)

  - Out of bounds write in ANGLE in Google Chrome prior to 91.0.4472.101 allowed a remote attacker to
    potentially perform out of bounds memory access via a crafted HTML page. (CVE-2021-30547)

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