New kdebase packages are available for Slackware 12.0 to fix security issues. A long URL padded with spaces could be used to display a false URL in Konqueror's addressbar, and KDM when used with no-password login could be tricked into logging a different user in without a password. This is not the way KDM is configured in Slackware by default, somewhat mitigating the impact of this issue.
