Memory corruption via unchecked webpage parameter
Published Feb 24, 2021 · Updated Sep 17, 2024
Stack-based buffer overflow in VOICEYE WSActiveBridgeES before 2.1.0.3 allows attackers to corrupt memory through a crafted webpage. The bridge fails to bounds-check an attacker-controlled webpage parameter before writing it to a stack buffer; the affected function is undisclosed. The attack requires local access and user interaction, and successful exploitation corrupts memory within the bridge process security context.
