The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2024-2410 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 this issue but has instead relied only on the applicationโ€™s self-reported version number.
