Issue Overview:

A flaw was found in graphviz. A wrong assumption in record_init function leads to an off-by-one write in parse_reclbl function, allowing an attacker who can provide graph input to potentially execute code when the label of a node is invalid and shorter than two characters. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-18032)
