Red Hat Product Errata RHSA-2004:174 0 normal SHIPPED_LIVE Moderate: utempter security update 2004-05-26 04:00:00 UTC

Description Mark J. Cox 2004-04-20 15:47:49 UTC 
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.
