CVE-2020-18032

Un Desbordamiento de Búfer en Graphviz Graph Visualization Tools desde el ID del commit f8b9e035 y versiones anteriores, permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (bloqueo de la aplicación) al cargar un archivo diseñado en el componente "lib/common/shapes.c"

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.

It was discovered that graphviz contains null pointer dereference vulnerabilities. Exploitation via a specially crafted input file can cause a denial of service. This issue only affected Ubuntu 18.04 LTS. It was discovered that graphviz contains null pointer dereference vulnerabilities.
