PAM S/Key: Information disclosure PAM S/Key does not clear provided credentials from memory, allowing local attackers to gain access to cleartext credentials. pam_skey 2014-02-09 2014-02-09 482588 local 1.1.5-r5 1.1.5-r5

PAM S/Key is a pluggable authentication module for the OpenBSD Single-key Password system.

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

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

There is no known workaround at this time.

All PAM S/Key users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/pam_skey-1.1.5-r5"
CVE-2013-4285 a3li a3li
