Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Botan versions prior to 2.17.3

Description: The issue concerns certain decoding and encoding operations, specifically base32, base58, base64, and hex, where constant-time computations are not used. This could potentially lead to timing attacks.

Recommendations: For versions prior to 2.17.3, update to version 2.17.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of base32, base58, base64, and hex decoding and encoding operations until a patch is available.
