The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2021:5045 advisory.

  • Mozilla: JavaScript unexpectedly enabled for the composition area (CVE-2021-43528)

  • Mozilla: URL leakage when navigating while executing asynchronous function (CVE-2021-43536)

  • Mozilla: Heap buffer overflow when using structured clone (CVE-2021-43537)

  • Mozilla: Missing fullscreen and pointer lock notification when requesting both (CVE-2021-43538)

  • Mozilla: GC rooting failure when calling wasm instance methods (CVE-2021-43539)

  • Mozilla: External protocol handler parameters were unescaped (CVE-2021-43541)

  • Mozilla: XMLHttpRequest error codes could have leaked the existence of an external protocol handler (CVE-2021-43542)

  • Mozilla: Bypass of CSP sandbox directive when embedding (CVE-2021-43543)

  • Mozilla: Denial of Service when using the Location API in a loop (CVE-2021-43545)

  • Mozilla: Cursor spoofing could overlay user interface when native cursor is zoomed (CVE-2021-43546)

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