Graphviz push_subg() buffer overflow
| graphviz-pushsubg-bo (45765) |  High Risk |
Description:
Graphviz is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the push_subg() function. By persuading a victim to open a specially-crafted DOT file with a large number of Agraph_t elements, a remote attacker could overflow a buffer and execute arbitrary code on the system.
