Updated graphviz packages fix security vulnerabilities

Updated graphviz packages fix security vulnerabilities:

Multiple buffer overflow vulnerabilities in graphviz due to an error within the "yyerror()" function (lib/cgraph/scan.l) which can be exploited to cause a stack-based buffer overflow via a specially crafted file (CVE-2014-0978) and the acceptance of an arbitrarily long digit list by a regular expression matched against user input (CVE-2014-1236).
