The drv2.dll (aka RV20 decompression) module in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, RealPlayer Enterprise 2.1.2 and 2.1.3, Linux RealPlayer 11.0.2.1744, and possibly HelixPlayer 1.0.6 and other versions, allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted value of an unspecified length field in an RV20 video stream.
CVE-2010-4378 is a security vulnerability that . Impacting 3 products from realnetworks, from realnetworks, from linux organizations running these solutions should prioritize assessment and patching.
Documented in 2010, this vulnerability occurred amid the cloud computing expansion era, where traditional network perimeter security models were being reevaluated. Organizations were transitioning from isolated infrastructure to interconnected systems, creating new attack surfaces that vulnerabilities like this could exploit.

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.
