CVE-2006-6306: Format string vulnerability in Novell Modular Authentication Services (NMAS) in the Novell Client 4.91 SP2...

Security readout for executives and security teams

This issue affects Novell Client 4.91 SP2 and SP3 with NMAS. A person at the machine could enter specially formatted text in the logon username field and cause memory contents to be displayed or exposed. The practical risk depends on whether these legacy clients still exist on accessible workstations. Exposure is most likely on legacy endpoints still running Novell Client 4.91 SP2 or SP3, especially shared, kiosk, lab, or physically accessible systems. Modern environments without this client are unlikely to be affected. Prioritize discovery if the organization still has Novell Client deployments. This is not a broad internet-facing emergency, but legacy shared workstations could expose sensitive memory to anyone physically present. Mitigation focus: Inventory endpoints for Novell Client 4.91 SP2 or SP3.; Review Novell support advisories for vendor-approved fixes or upgrade guidance.; Remove unsupported Novell Client installations where no business need remains..
