Overview
Affected versions of this package are vulnerable to Symlink Attack in usersfile.c in the PAM module, which does expands ${HOME} and ${USER} as path elements when processing the OTP state file, AKA usersfile, as root. This allows an attacker to elevate privileges by exploiting the use of fchown in the presence of a symlink.
