Vulnerability Note VU#32448

Due to insecure creation of configuration files via KApplication-class, local users can create arbitrary files when running setuid root KDE programs

Original Release date: 30 May 2001 | Last revised: 30 May 2001

Overview

KApplication-class, a class used to create KDE applications, creates configuration files without checking for proper ownership or prior existence.

Description

KApplication-class, a class used to create KDE applications, creates configuration files. These files are created in a local directory and named predictably based on the KDE application name. The CREAT call does not check for prior existence or proper ownership.

Impact

Using a symlink attack, an attacker my cause corruption of any file writable by the user of the application. If the application is setuid root, an attacker may cause corruption of any file in the system.

Solution

Contact vendor for patches.

The system administrator could create configuration files for common applications, appropriately named and protected, to forestall the symlink attack, but this would not be a robust fix and may need to be reapplied frequently.
