Hi,
The following vulnerability was published for libcrypto++.
CVE-2019-14318[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
