Gilles Peskine 326ba3c0bb mbedtls_ssl_decrypt_buf(): fix buffer overread with stream cipher
With stream ciphers, add a check that there's enough room to read a MAC in
the record. Without this check, subtracting the MAC length from the data
length resulted in an integer underflow, causing the MAC calculation to try
reading (SIZE_MAX + 1 - maclen) bytes of input, which is a buffer overread.
