Ubuntu 18.04 LTS : Yubico PIV Tool vulnerabilities (USN-4276-1)

High Nessus Plugin ID 133648


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that libykpiv, a supporting library of the Yubico PIV Tool and YubiKey PIV Manager, mishandled specially crafted input.
An attacker with a custom-made, malicious USB device could potentially execute arbitrary code on a computer running the Yubico PIV Tool or Yubikey PIV Manager.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libykpiv1, ykcs11 and / or yubico-piv-tool packages.
