Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in the Windows Remote Desktop Client enables unauthenticated network attackers to execute arbitrary code on a connecting client system by exploiting a heap-based buffer overflow triggered when the client processes a maliciously crafted RDP server response. All major Windows 10, Windows 11, and Windows Server editions from 2012 through 2025 are affected across x86, x64, and ARM64 architectures. …
