<p>PAM S/Key is a pluggable authentication module for the OpenBSD
Single-key Password system.
<p>Ulrich Müller reported that a Gentoo patch to PAM S/Key does not remove
credentials provided by the user from memory.
<impact type="normal">
<p>A local attacker with privileged access could inspect a memory dump to
gain access to cleartext credentials provided by users.
<p>There is no known workaround at this time.</p>
<p>All PAM S/Key users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=sys-auth/pam_skey-1.1.5-r5"
