CVE-2019-14318

Summary
Assigner-mitre
Assigner Org ID-8254265b-2729-46b6-b9e3-3dfca2d5bfca

Credits

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.

Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory after an assertion failure, as demonstrated by reading a core dump.
