Yubico have released version 1.0.8 of pam-u2f containing two security fixes that together could allow a local user to read any file on the filesystem if the debug variable and the debug_file variables have been set in the pam module configuration. Also, the authfile setting file in the users home directory was parsed as root and would follow symlinks which could be abused in many ways. https://developers.yubico.com/pam-u2f/Release_Notes.html This was discovered by SUSE and they will make a post to oss-security@ soon.
