Kerentanan Improper Restriction of Operations within the Bounds of a Memory Buffer pada riot-os riot. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

RIOT 2020.04 has a buffer overflow in the base64 decoder. The decoding function base64_decode() uses an output buffer estimation function to compute the required buffer capacity and validate against the provided buffer size. The base64_estimate_decode_size() function calculates the expected decoded size with an arithmetic round-off error and does not take into account possible padding bytes. Due to this underestimation, it may be possible to craft base64 input that causes a buffer overflow.
