Descriptions

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.

RIOT es un sistema operativo multiproceso en tiempo real que admite una variedad de dispositivos que suelen ser microcontroladores de 8, 16 y 32 bits. La función `_on_rd_init()` no implementa una verificación de tamaño antes de copiar datos al búfer estático `_result_buf`. Si un atacante puede crear un payload lo suficientemente larga, podría provocar un desbordamiento del búfer. Si la entrada no verificada anterior está controlada por un atacante y cruza un límite de seguridad, el impacto de la vulnerabilidad de desbordamiento del búfer podría variar desde denegación de servicio hasta ejecución de código arbitrario. Este problema aún no se ha solucionado. Se recomienda a los usuarios que agreguen la verificación manual de los límites.

RIOT versions 2024.01 and below suffers from multiple buffer overflows, ineffective size checks, and out-of-bounds memory access vulnerabilities.
