RHEL 2.1 / 3 : utempter (RHSA-2004:174)

Low Nessus Plugin ID 12490


The remote Red Hat host is missing a security update.


An updated utempter package that fixes a potential symlink vulnerability is now available.

Utempter is a utility that allows terminal applications such as xterm and screen to update utmp and wtmp without requiring root privileges.

Steve Grubb discovered a flaw in Utempter which allowed device names containing directory traversal sequences such as '/../'. In combination with an application that trusts the utmp or wtmp files, this could allow a local attacker the ability to overwrite privileged files using a symlink.

Users should upgrade to this new version of utempter, which fixes this vulnerability.


Update the affected utempter package.
