The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:3559 advisory.

  • Mozilla: Integer overflow in nsJPEGEncoder::emptyOutputBuffer (CVE-2020-12422)

  • Mozilla: WebRTC permission prompt could have been bypassed by a compromised content process (CVE-2020-12424)

  • Mozilla: Out of bound read in Date.parse() (CVE-2020-12425)

  • Mozilla: X-Frame-Options bypass using object or embed tags (CVE-2020-15648)

  • Mozilla: Bypassing iframe sandbox when allowing popups (CVE-2020-15653)

  • Mozilla: Custom cursor can overlay user interface (CVE-2020-15654)

  • Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)

  • Mozilla: Overriding file type when saving to disk (CVE-2020-15658)

  • Mozilla: Attacker-induced prompt for extension installation (CVE-2020-15664)

  • Mozilla: Use-After-Free when aborting an operation (CVE-2020-15669)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
