From Red Hat Security Advisory 2020:2966 :
The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:2966 advisory.
Mozilla: Information disclosure due to manipulated URL object (CVE-2020-12418)
Mozilla: Use-after-free in nsGlobalWindowInner (CVE-2020-12419)
Mozilla: Use-After-Free when trying to connect to a STUN server (CVE-2020-12420)
Mozilla: Add-On updates did not respect the same certificate trust rules as software updates (CVE-2020-12421)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
