A vulnerability was discovered and corrected in graphviz: Stack-based buffer overflow in the push_subg function in parser.y in Graphviz 2.20.2, and possibly earlier versions, allows user-assisted remote attackers to cause a denial of service or execute arbitrary code via a DOT file with a large number of Agraph_t elements . This update provides a fix for this vulnerability. Update: Packages for 2008.0 are being provided due to extended support for Corporate products.
