In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.

  • CVE-2023-34414: Click-jacking certificate exceptions through rendering lag (high)
    The error page for sites with invalid TLS certificates was missing the
    activation-delay Thunderbird uses to protect prompts and permission dialogs
    from attacks that exploit human response time delays. If a malicious
    page elicited user clicks in precise locations immediately before
    navigating to a site with a certificate error and made the renderer
    extremely busy at the same time, it could create a gap between when
    the error page was loaded and when the display actually refreshed.
    With the right timing the elicited clicks could land in that gap and
    activate the button that overrides the certificate error for that site.

  • CVE-2023-34416: Memory safety bugs fixed in Thunderbird 102.12 (high)
    Mozilla developers and community members Gabriele Svelto, Andrew McCreight,
    the Mozilla Fuzzing Team, Sean Feng, and Sebastian Hengst reported memory
    safety bugs present in Thunderbird 102.11. 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.
