Detailsinfo

A vulnerability classified as problematic was found in Crypto++ up to 8.3.0. This vulnerability affects an unknown part of the file ecp.cpp of the component ECDSA Signature Handler. The manipulation with an unknown input leads to a path error vulnerability. The CWE definition for the vulnerability is CWE-417. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The weakness was presented 07/30/2019 (Website). The advisory is shared for download at openwall.com. This vulnerability was named CVE-2019-14318 since 07/27/2019. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
