Name of the Vulnerable Software and Affected Versions Graphviz versions 2.39.20160612.1140

Description The issue is related to a NULL pointer dereference in the agroot() function, which can be exploited to cause a denial of service. This function is part of the Graphviz application for graph visualization.
