login in util-linux-2.12a skips pam_acct_mgmt and chauth_tok when authentication is skipped, such as when a Kerberos krlogin session has been established, which might allow users to bypass intended access policies that would be enforced by pam_acct_mgmt and chauth_tok.

From Red Hat Security Advisory 2007:0235 :

An updated util-linux package that corrects a security issue and fixes several bugs is now available.

This update has been rated as having low security impact by the Red Hat Security Response Team.

The util-linux package contains a collection of basic system utilities.

A flaw was found in the way the login process handled logins which did not require authentication. Certain processes which conduct their own authentication could allow a remote user to bypass intended access policies which would normally be enforced by the login process.
(CVE-2006-7108)

This update also fixes the following bugs :

* The partx, addpart and delpart commands were not documented.

* The 'umount -l' command did not work on hung NFS mounts with cached data.

* The mount command did not mount NFS V3 share where sec=none was specified.

* The mount command did not read filesystem LABEL from unpartitioned disks.

* The mount command did not recognize labels on VFAT filesystems.

* The fdisk command did not support 4096 sector size for the '-b' option.

* The mount man page did not list option 'mand' or information about /etc/mtab limitations.

All users of util-linux should upgrade to these updated packages, which contain backported patches to correct these issues.

Updated packages have been patched to address this issue.
