The Linux-PAM package before 1.5.2-6.1 for openSUSE Tumbleweed allows
authentication bypass for SSH logins. The pam_access.so module doesn't
correctly restrict login if a user tries to connect from an IP address
that is not resolvable via DNS. In such conditions, a user with denied
access to a machine can still get access. NOTE: the relevance of this
issue is largely limited to openSUSE Tumbleweed and openSUSE Factory;
it does not affect Linux-PAM upstream.
