Description

It was discovered that graphviz incorrectly handled parsing errors. An attacker could use this issue to cause graphviz to crash or possibly execute arbitrary code.

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