The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:1351 advisory.

  • Mozilla: More internal network hosts could have been probed by a malicious webpage (CVE-2021-23961)

  • Mozilla: Out of bound write due to lazy initialization (CVE-2021-23994)

  • Mozilla: Use-after-free in Responsive Design Mode (CVE-2021-23995)

  • Mozilla: Secure Lock icon could have been spoofed (CVE-2021-23998)

  • Mozilla: Blob URLs may have been granted additional privileges (CVE-2021-23999)

  • Mozilla: Arbitrary FTP command execution on FTP servers using an encoded URL (CVE-2021-24002)

  • Mozilla: Incorrect size computation in WebAssembly JIT could lead to null-reads (CVE-2021-29945)

  • Mozilla: Port blocking could be bypassed (CVE-2021-29946)

  • Mozilla: Race condition when reading from disk while verifying signatures (CVE-2021-29948)

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