Vulnerability from github – Published: 2021-08-25 20:46 – Updated: 2023-08-25 00:12

Summary

libsecp256k1 contains side-channel timing attack

Details

Versions of libsecp256k1 prior to 0.3.1 did not execute Scalar::check_overflow in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying Scalar::check_overflow to execute in constant time.

Severity ?

7.5 (High)
