Azure RTOS USBX vulnerable to buffer overflow

Azure RTOS USBX is a USB host, device, and on-the-go (OTG) embedded stack, that is fully integrated with Azure RTOS ThreadX. Prior to version 6.1.12, the USB DFU UPLOAD functionality may be utilized to introduce a buffer overflow resulting in overwrite of memory contents. In particular cases this may allow an attacker to bypass security features or execute arbitrary code. The implementation of `ux_device_class_dfu_control_request` function prevents buffer overflow during handling of DFU UPLOAD command when current state is `UX_SYSTEM_DFU_STATE_DFU_IDLE`. This issue has been patched, please upgrade to version 6.1.12. As a workaround, add the `UPLOAD_LENGTH` check in all possible states.

Azure RTOS USBX 安全漏洞

Azure RTOS USBX是Azure RTOS开源的一个 USB 主机、设备和移动 (OTG) 嵌入式堆栈。与 Azure RTOS ThreadX 完全集成，可用于所有支持 Azure RTOS ThreadX 的处理器。 Azure RTOS USBX 6.1.12之前版本存在安全漏洞，该漏洞源于USB DFU上传功能可用于引入缓冲区溢出，从而导致内存内容被覆盖，这可能允许攻击者绕过安全功能执行任意代码。
