Lack of size check and buffer overflow in RIOT
Summary
Lack of size check and buffer overflow in RIOT
Original description
The description as published by the source.
RIOT is a real-time multi-threading operating system that supports a range of devices that are typically 8-bit, 16-bit and 32-bit microcontrollers. The _on_rd_init() function does not implement a size check before copying data to the _result_buf static buffer. If an attacker can craft a long enough payload, they could cause a buffer overflow. If the unchecked input above is attacker-controlled and crosses a security boundary, the impact of the buffer overflow vulnerability could range from denial of service to arbitrary code execution. This issue has yet to be patched. Users are advised to add manual bounds checking.
