An utempter update for Fedora Core 1 has been released

Fedora Update Notification

Name : utempter
Version : 0.5.5
Release : 3.FC1.0
Summary : A privileged helper for utmp/wtmp updates.
Description :
Utempter is a utility which allows some non-privileged programs to have required root access without compromising system security. Utempter accomplishes this feat by acting as a buffer between root and the programs.

Update Information:

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

Problem Description:
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.
