According to the versions of the harfbuzz packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  • 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
