KDE Project Security Advisory ============================= Title: plasma-workspace: Network access from screen locker Risk Rating: Low CVE: CVE-2015-1307 Platforms: X11 Versions: plasma-workspace < 5.1.95 Author: Martin Gräßlin mgraesslin@kde.org Date: 22 January 2015 Overview ======== Plasma's lock screen implementation uses Look and Feel packages containing QtQuick source files to style the lock screen. Look and Feel packages can be selected by the user using a system settings module. A user could download a Look and Feel package and install it locally. The QtQuick view allows network interaction, thus a malicious Look and Feel package could collect the user's passwords on all systems it's installed to. Similarly any application running under the given user could install a different Look and Feel package to gain the user's password. Impact ====== If a user downloaded and installed a Look and Feel package the user's password might be sent to the author of the Look and Feel package. Workaround ========== Use one of the default provided Look and Feel packages. Solution ======== For plasma-workspace upgrade to Plasma 5.1.95 or apply the following patch: http://commits.kde.org/plasma-workspace/0a9cea625dfcb068fb03a4deab7430b1c4ad8aa4 Credits ======= Thanks to Martin Gräßlin for finding and fixing the issue.
