Heap-based buffer overflow in Real Networks Helix Server and Helix Mobile Server before 11.1.3, and Helix DNA Server 11.0 and 11.1, allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a DESCRIBE request that contains an invalid LoadTestPassword field.
CVE-2006-6026 is a security vulnerability that . Impacting 3 products from realnetworks, from realnetworks, from realnetworks organizations running these solutions should prioritize assessment and patching.
Originally identified in 2006, 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 realnetworks'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.
