Hello,

Graphviz, a collection of tools for the manipulation and layout of graphs, was recently reported to be affected by a buffer overflow vulnerability.

The vulnerability is caused due to an error within the "yyerror()" function (lib/cgraph/scan.l) and can be exploited to cause a stack-based buffer overflow via a specially crafted file.

Can a CVE please be assigned to this issue?
