MGASA-2022-0162 - Updated firefox packages fix security vulnerability

Publication date: 06 May 2022
URL: https://advisories.mageia.org/MGASA-2022-0162.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-29909,
     CVE-2022-29911,
     CVE-2022-29912,
     CVE-2022-29914,
     CVE-2022-29916,
     CVE-2022-29917

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-2022-29909).

Firefox did not properly protect against top-level navigations for an iframe
sandbox with a policy relaxed through a keyword like
allow-top-navigation-by-user-activation (CVE-2022-29911).

Requests initiated through reader mode did not properly omit cookies with a
SameSite attribute (CVE-2022-29912).

When reusing existing popups Firefox would have allowed them to cover the
fullscreen notification UI, which could have enabled browser spoofing attacks
(CVE-2022-29914).

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-2022-29916).

Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the
Mozilla Fuzzing Team reported memory safety bugs present in 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-2022-29917).
