MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA
signature generation. This allows a local or a remote attacker, able to
measure the duration of hundreds to thousands of signing operations, to
compute the private key used. The issue occurs because
crypto/pubkey/ecc_math.c scalar multiplication leaks the bit length of the
scalar.
