CVE-2019-12209

Priority
Description
Yubico pam-u2f 1.0.7 attempts parsing of the configured authfile (default
$HOME/.config/Yubico/u2f_keys) as root (unless openasuser was enabled), and
does not properly verify that the path lacks symlinks pointing to other
files on the system owned by root. If the debug option is enabled in the
PAM configuration, part of the file contents of a symlink target will be
logged, possibly revealing sensitive information.
