The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:5427 advisory.

  • firefox: use-after-free in workers (CVE-2023-3600)

  • Mozilla: Out-of-bounds write in PathOps (CVE-2023-5169)

  • Mozilla: Use-after-free in Ion Compiler (CVE-2023-5171)

  • Mozilla: Memory safety bugs fixed in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3 (CVE-2023-5176)

  • libvpx: Heap buffer overflow in vp8 encoding in libvpx (CVE-2023-5217)

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