Vulnerability Assessment Details

RHSA-2004-174: utempter

Vulnerability Assessment Summary
Check for the version of the utempter packages

Detailed Explanation for this Vulnerability Assessment


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

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

Steve Grubb discovered a flaw in Utempter which permited device names
containing directory traversal sequences such as '/../'. In combination
with an application that trusts the utmp or wtmp files, this could permit 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.
