issues including arbitrary code execution, content spoofing,
information disclosure, privilege escalation and insufficient
validation.

The problems have been fixed upstream in version 100.0.

Workaround

None.

Description

• CVE-2022-29909 (privilege escalation)

Documents in deeply-nested cross-origin browsing contexts could have
obtained permissions granted to the top-level origin, bypassing the
existing prompt and wrongfully inheriting the top-level permissions.

• CVE-2022-29911 (arbitrary code execution)

An improper implementation of the new iframe sandbox keyword allow-top-
navigation-by-user-activation could lead to script execution without
allow-scripts being present.

• CVE-2022-29912 (insufficient validation)

Requests initiated through reader mode did not properly omit cookies
with a SameSite attribute.

• CVE-2022-29914 (content spoofing)

When reusing existing popups Firefox would have allowed them to cover
the fullscreen notification UI, which could have enabled browser
spoofing attacks.

• CVE-2022-29915 (information disclosure)

The Performance API did not properly hide the fact whether a request
cross-origin resource has observed redirects.

• CVE-2022-29916 (information disclosure)

Firefox behaved slightly differently for already known resources when
loading CSS resources involving CSS variables. This could have been
used to probe the browser history.

• CVE-2022-29917 (arbitrary code execution)

Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and
the Mozilla Fuzzing Team reported memory safety bugs present in Firefox
99 and Firefox ESR 91.8. 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-2022-29918 (arbitrary code execution)

Mozilla developers Gabriele Svelto, Randell Jesup and the Mozilla
Fuzzing Team reported memory safety bugs present in Firefox 99. 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.
