KDE before 3.3.0 does not properly handle when certain symbolic links point to stale locations, which could allow local users to create or truncate arbitrary files.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
Kde Kde * 3.3 (excluding)
Red Hat Enterprise Linux 3 RedHat kdebase-6:3.1.3-5.4 *
Red Hat Enterprise Linux 3 RedHat kdelibs-6:3.1.3-6.6 *

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
