vulnerabilities as referenced in the mfsa2023-20 advisory.

  - The error page for sites with invalid TLS certificates was missing the activation-delay Firefox 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-2023-34414)

  - When choosing a site-isolated process for a document loaded from a data: URL that was the result of a
    redirect, Firefox would load that document in the same process as the site that issued the redirect. This
    bypassed the site-isolation protections against Spectre-like attacks on sites that host an open
    redirect. Firefox no longer follows HTTP redirects to data: URLs. (CVE-2023-34415)

  - Mozilla developers and community members Gabriele Svelto, Andrew McCreight, the Mozilla Fuzzing Team, Sean
    Feng, and Sebastian Hengst reported memory safety bugs present in Firefox 113 and Firefox ESR 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. (CVE-2023-34416)
