Insight
Insight
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 allows terminal applications such as xterm and screen to update /var/run/utmp and /var/log/wtmp without requiring root privileges. Steve Grubb has identified an issue with utempter-0.5.2 where under certain circumstances an attacker 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.
