Stack-based buffer overflow in the push_subg function in parser.y (lib/graph/parser.c) in Graphviz 2.20.2, and possibly earlier versions, allows user-assisted remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via a DOT file with a large number of Agraph_t elements.
CVE-2008-4555 is a security vulnerability that . Impacting 1 product from graphviz organizations running these solutions should prioritize assessment and patching.
Originally identified in 2008, this vulnerability predates many modern security frameworks and practices. The vulnerability landscape of that era was characterized by different threat models and less mature defense mechanisms compared to contemporary standards.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For graphviz's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
