An issue was discovered in libcdtdttree.c in libcdt.a in graphviz 2.40.1. Stack consumption occurs because of recursive agclose calls in libcgraphgraph.c in libcgraph.a, related to agfstsubg in libcgraphsubg.c.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
