The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0914 advisory.

  • usrsctp: Out of bounds reads in sctp_load_addresses_from_init() (CVE-2019-20503)

  • Mozilla: Use-after-free when removing data about origins (CVE-2020-6805)

  • Mozilla: BodyStream::OnInputStreamReady was missing protections against state confusion (CVE-2020-6806)

  • Mozilla: Use-after-free in cubeb during stream destruction (CVE-2020-6807)

  • Mozilla: Devtools’ ‘Copy as cURL’ feature did not fully escape website-controlled data, potentially leading to command injection (CVE-2020-6811)

  • Mozilla: The names of AirPods with personally identifiable information were exposed to websites with camera or microphone permission (CVE-2020-6812)

  • Mozilla: Memory safety bugs fixed in Firefox 74 and Firefox ESR 68.6 (CVE-2020-6814)

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