This is an update fixing format string vulnerability in cgraph.

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

Format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz allows remote attackers to have unspecified impact via format string specifiers in unknown vector, which are not properly handled in an error string.

Joshua Rogers discovered a format string vulnerability in the yyerror 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.
