The agroot() function in cgraph\obj.c in libcgraph.a in Graphviz 2.39.20160612.1140 has a NULL pointer dereference, as demonstrated by graphml2gv.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - graphviz: format string vulnerability in yyerror() (CVE-2014-9157)

  - graphviz: null pointer dereference in function agroot() in cgraph\obj.c (CVE-2019-11023)

  - An issue was discovered in lib\cdt\dttree.c in libcdt.a in graphviz 2.40.1. Stack consumption occurs     because of recursive agclose calls in lib\cgraph\graph.c in libcgraph.a, related to agfstsubg in     lib\cgraph\subg.c. (CVE-2019-9904)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
