Code execution via undisclosed stack buffer overflow
Published Jul 7, 2026 · Updated Jul 7, 2026
Stack-based buffer overflow in Labcenter Proteus Design Suite 9.1 SP4 Build 42914 allows attackers to execute arbitrary code. CISA and Labcenter have not published the affected parser, input format, or unsafe operation that overruns the stack buffer. Exploitation requires local delivery of attacker-controlled input and active user interaction, with successful code execution in the Proteus process context.
