SSA-2004-110-01 utempter security update

Vulnerability Assessment Summary
SSA-2004-110-01 utempter security update

Detailed Explanation for this Vulnerability Assessment

New utempter packages are available for Slackware 9.1 and -current to
fix a security issue. (Slackware 9.1 was the first version of Slackware
to use the libutempter library, and earlier versions of Slackware are
not affected by this issue)

The utempter package provides a utility and shared library that
permits terminal applications such as xterm and screen to update
/var/run/utmp and /var/log/wtmp without requiring root rights.
Steve Grubb has identified an issue with utempter-0.5.2 where
under certain circumstances a possible hacker could cause it to
overwrite files through a symlink. This has been addressed by
upgrading the utempter package to use Dmitry V. Levin's new
implementation of libutempter that does not have this bug.
