Graphviz 2.36.0 through 9.x before 10.0.1 has an out-of-bounds read via a crafted config6a file. NOTE: exploitability may be uncommon because this file is typically owned by root.
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.
