Description
The `ecdsa` PyPI package is a pure Python implementation of ECC (Elliptic Curve Cryptography) with support for ECDSA (Elliptic Curve Digital Signature Algorithm), EdDSA (Edwards-curve Digital Signature Algorithm) and ECDH (Elliptic Curve Diffie-Hellman). Versions 0.18.0 and prior are vulnerable to the Minerva attack. As of time of publication, no known patched version exists.
Weaknesses (CWE)
- CWE-203 — Observable Discrepancy
- CWE-208 — Observable Timing Discrepancy
- CWE-385 — Covert Timing Channel
