KApplication-class, a class used to create KDE applications, creates configuration files without checking for proper ownership or prior existence.
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.
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.
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.
The initial report of this vulnerability was made by Sebastian Krahmer.
