Stack-based buffer overflow in the yyerror function in lib/cgraph/scan.l in Graphviz 2.34.0 allows remote attackers to have unspecified impact via a long line in a dot file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
