The version of Thunderbird installed on the remote Windows host is prior to 68.9.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-22 advisory.

  • NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. (CVE-2020-12399)

  • When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash. (CVE-2020-12405)

  • Mozilla developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. (CVE-2020-12406)

  • Mozilla developers Tom Tung and Karl Tomlinson reported memory safety bugs present in Firefox 68.8. 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. (CVE-2020-12410)

  • If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection. (CVE-2020-12398)

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