"value": "Sandboxie-Plus is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, several ProcessServer handlers (KillAllHandler, SuspendAllHandler, and RunSandboxedHandler) copy a WCHAR boxname[34] field from request structures into WCHAR[40] stack buffers using wcscpy without verifying null termination. Because the service pipe accepts variable-length packets larger than the request structure, an attacker can fill the boxname field with non-zero data and append additional controlled wide characters after the structure. wcscpy then reads past the fixed field and overflows the destination stack buffer. The service pipe is created with a NULL DACL, allowing any local process to connect, and the unsafe copy occurs before authorization checks. This can lead to a crash of the SbieSvc service or potential code execution as SYSTEM. This issue has been fixed in version 1.17.3."
