Title:	RedHat Security Advisory RHSA-2003:028
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2003:028. The pam_xauth module is used to forward xauth information from user to user in applications such as the su command. Andreas Beck discovered that pam_xauth will forward authorization information from the root account to unprivileged users. This could be used by a local attacker to gain access to an administrator's X session. To exploit this vulnerability the attacker would have to get the administrator, as root, to use su to access the account belonging to the attacker. Users of pam_xauth are advised to upgrade to these errata packages which contain a patch which adds ACL (access control list) functionality to pam_xauth and disallows root forwarding by default. Thanks to Andreas Beck for reporting this issue. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2003-028.html http://www.redhat.com/support/wpapers/redhat/newpam/tinkering.html Risk factor : High CVSS Score: 7.2
