Name of the Vulnerable Software and Affected Versions
Yubico YubiKey versions 5.4.1 through 5.7.3
Description
The issue is related to an incorrect implementation of the FIDO CTAP PIN/UV 2 authentication protocol. Specifically, it uses the signature length from the CTAP PIN/UV 1 protocol, even when the CTAP PIN/UV 2 protocol is chosen, resulting in partial signature verification.
Recommendations
For versions 5.4.1 through 5.7.3, update to version 5.7.4 or later to resolve the issue.
