    Ulrich Müller reported that a Gentoo patch to PAM S/Key does not remove
      credentials provided by the user from memory.
  
Impact :

    A local attacker with privileged access could inspect a memory dump to
      gain access to cleartext credentials provided by users.
  
Workaround :

    There is no known workaround at this time."
