Updated firefox packages fix a security vulnerability

Publication date: 08 Jun 2021
Type: security
Affected Mageia releases : 7 , 8
CVE: CVE-2021-29967


Updated firefox packages fix a security vulnerability:

Mozilla developers Gabriele Svelto, Anny Gakhokidze, Alexandru Michis,
Christian Holler reported memory safety bugs present in Firefox 88 and
Firefox ESR 78.11. 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-2021-29967).

Memory safety bugs fixed in Firefox 89 and Firefox ESR 78.11

This update also fixes:
- Unable to connect to Element with the firefox ESR packaged by Mageia
  (Bug 28755).
- Crashes on certain webpages with our packaged version (Bug 28652).
- Some connections to websites like Santander Bank (Bug 28359).
- Neither audio nor video with BigBlueButton and other WebRTC services
  with our packaged version of Firefox ESR (Bug 27374).
