Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA
signature generation. This allows a local or remote attacker, able to
measure the duration of hundreds to thousands of signing operations,
to compute the private key used. The issue occurs because scalar
multiplication in ecp.cpp (prime field curves, small leakage) and
algebra.cpp (binary field curves, large leakage) is not constant time
and leaks the bit length of the scalar among other information
(CVE-2019-14318).");
