- Summary
- Azure RTOS USBX vulnerable to buffer overflow
- Details
-
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_requestfunction prevents buffer overflow during handling of DFU UPLOAD command when current state isUX_SYSTEM_DFU_STATE_DFU_IDLE. This issue has been patched, please upgrade to version 6.1.12. As a workaround, add theUPLOAD_LENGTHcheck in all possible states. - Database specific
