Detailsinfo

A vulnerability, which was classified as critical, was found in python-ecdsa up to 0.18.0 (Programming Language Software). Affected is an unknown functionality. The manipulation with an unknown input leads to a covert timing channel vulnerability. CWE is classifying the issue as CWE-385. Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was disclosed 01/23/2024 as GHSA-wj6h-64fc-37mp. The advisory is available at github.com. This vulnerability is traded as CVE-2024-23342 since 01/15/2024. The technical details are unknown and an exploit is not available.
