Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Botan before 1.10.13 and 1.11.x before 1.11.29 do not use a constant-time algorithm to perform a modular inverse on the signature nonce k, which might allow remote attackers to obtain ECDSA secret keys via a timing side-channel attack.


Remediation

Install update from vendor's website.
