Application crash via oversized computer name
Published Mar 21, 2026 · Updated Mar 21, 2026
Local buffer overflow in LizardSystems Terminal Services Manager 3.2.1 allows local users to crash the application through a server name. The Add Computer dialog accepts a 5,000-byte value in the Computer name or IP address field without enforcing the destination buffer's bounds. Exploitation requires access to the local GUI to add and later open the crafted server entry, interrupting only the management application.
