The kdebase packages provide the core applications for KDE, the K Desktop Environment. These core packages include Konqueror, the web browser and file manager.
These updated packages address the following vulnerabilities:
Kees Huijgen found a flaw in the way KDM handled logins when autologin and "shutdown with password" were enabled. A local user would have been able to login via KDM as any user without requiring a password. (CVE-2007-4569)
Two Konqueror address spoofing flaws were discovered. A malicious web site could spoof the Konqueror address bar, tricking a victim into believing the page was from a different site. (CVE-2007-3820, CVE-2007-4224)
Users of KDE should upgrade to these updated packages, which contain backported patches to correct these issues.
