The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2021:1651-1 advisory.

  • Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted file into the lib/common/shapes.c component. (CVE-2020-18032)

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