New sudo packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/sudo-1.8.28-i586-1_slack14.2.txz: Upgraded.
Fixed a bug where an sudo user may be able to run a command as root when
the Runas specification explicitly disallows root access as long as the
ALL keyword is listed first.
For more information, see:
