Description

Spybreak discovered a problem in scrollkeeper, a free electronic cataloging system for documentation. The scrollkeeper-get-cl program creates temporary files in an insecure manner in /tmp using guessable filenames. Since scrollkeeper is called automatically when a user logs into a Gnome session, an attacker with local access can easily create and overwrite files as another user.
