The SMB Mailslot parsing functionality in PAM in multiple ISS products with XPU (24.39/1.78/epj/x.x.x.1780), including Proventia A, G, M, Server, and Desktop, BlackICE PC and Server Protection 3.6, and RealSecure 7.0, allows remote attackers to cause a denial of service (infinite loop) via a crafted SMB packet that is not properly handled by the SMB_Mailslot_Heap_Overflow decode.
CVE-2006-3840 is a security vulnerability that . Impacting 10 products from iss, from iss, from iss and 7 others, 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 iss'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.
