Description

The remote host is affected by the vulnerability described in GLSA-200811-04 (Graphviz: User-assisted execution of arbitrary code)

Roee Hay reported a stack-based buffer overflow in the push_subg()     function in parser.y when processing a DOT file with a large number of     Agraph_t elements.

Impact :

A remote attacker could entice a user or automated system to open a     specially crafted DOT file in an application using Graphviz, possibly     leading to the execution of arbitrary code.

Workaround :

There is no known workaround at this time.
