CVE-2020-15350

RIOT 2020.04 has a buffer overflow in the base64 decoder. The decoding function base64decode uses an output buffer estimation function to compute the required buffer capacity and validate against the provided buffer size. The base64estimatedecodesize function calculates the expected decoded size...
