Since yesterday, Tuesday, new versions of the popular Firefox web browser in the form of the major release 82 and the ESR version (Extended Support Release) 78. 4 available. Security gaps were closed in both editions, some of which are believed to be a high risk. Firefox 82 received a total of seven vulnerability fixes, with ESR there were two.

Security updates Four gaps with “High” rating (CVE – 2020 – 15969, CVE – 2020 – 15254, CVE – 2020 – 15683 and CVE – 2020 – 15684) in Firefox versions prior to version 82 could have been abused by remote attackers to cause exploitable browser crashes to provoke and, in the worst case, to execute arbitrary program code. Against CVE – 2020 – 15969 and CVE – 2020 – 15683 the ESR output of the Firefox browser was also secured.

Mozilla provides further details in the Security Advisories for the new versions:
