CVE-2012-6140: Infoleak
First published: Thu Apr 18 2013(Updated: )
An information disclosure file was found in the way google-authenticator, a pluggable authentication module (PAM) which allows login using one-time passcodes conforming to the open standards developed by the Initiative for Open Authentication (OATH), performed management of its secret / state file in certain configurations. Due the lack of 'user=' option the secret file was previously required to be user-readable, allowing (in certain cases) a local attacker to obtain the (pre)shared client-to-authentication-server secret, possibly leading to victim's account impersonation.
