The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2020:3345 advisory.
Mozilla: Potential leak of redirect targets when loading scripts in a worker (CVE-2020-15652)
Mozilla: Memory safety bugs fixed in Firefox 79 and Firefox ESR 68.11 (CVE-2020-15659)
chromium-browser: Use after free in ANGLE (CVE-2020-6463)
chromium-browser: Inappropriate implementation in WebRTC (CVE-2020-6514)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
