The remote Fedora 38 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-a48406ecd2 advisory.

  • hb-ot-layout-gsubgpos.hh in HarfBuzz through 6.0.0 allows attackers to trigger O(n^2) growth via consecutive marks during the process of looking back for base glyphs when attaching marks.
    (CVE-2023-25193)

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