The server driver (srv.sys) in Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service (system crash) via an SMB_COM_TRANSACTION SMB message that contains a string without null character termination, which leads to a NULL dereference in the ExecuteTransaction function, possibly related to an "SMB PIPE," aka the "Mailslot DOS" vulnerability. NOTE: the name "Mailslot DOS" was derived from incomplete initial research; the vulnerability is not associated with a mailslot.
CVE-2006-3942 is a security vulnerability that . Impacting 3 products from microsoft, from microsoft, from microsoft 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 microsoft'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.
