Updated kdebase packages that correct a security flaw in kdm are now
available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
The kdebase packages provide the core applications for KDE, the K Desktop
Environment. These core packages include the KDE Display Manager (KDM).
Ludwig Nussel discovered a flaw in KDM. A malicious local KDM user could
use a symlink attack to read an arbitrary file that they would not normally
have permissions to read. (CVE-2006-2449)
Note: this issue does not affect the version of KDM as shipped with Red Hat
Enterprise Linux 2.1 or 3.
All users of KDM should upgrade to these updated packages which contain a
backported patch to correct this issue.
