function in lib/cgraph/scan.l in Graphviz, a rich set of graph drawing
tools. An attacker could use this flaw to cause graphviz to crash or
possibly execute arbitrary code.

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