Eric Sesterhenn of X41 D-Sec notified Yubico of a security issue in libykpiv, a supporting library of the Yubico PIV Tool, YubiKey PIV Manager, and Yubikey Smart Card Minidriver. This issue can allow an attacker with a custom made malicious USB device masquerading as a YubiKey, and physical access to a computer where the Yubico PIV Tool, YubiKey PIV Manager, or YubiKey Smart Card Minidriver is running, to potentially execute arbitrary code on that computer.
It is not possible to perform this attack with a genuine YubiKey, however, we recommend updating all necessary software included below.
