Name of the Vulnerable Software and Affected Versions KDE kdelibs versions prior to 4.14.32 KAuth versions prior to 5.34

Description The issue allows local users to gain root privileges by spoofing a callerID and leveraging a privileged helper app. This can be exploited by local users to elevate their privileges.

Recommendations For KDE kdelibs versions prior to 4.14.32, update to version 4.14.32 or later. For KAuth versions prior to 5.34, update to version 5.34 or later. As a temporary workaround, consider restricting access to privileged helper apps until a patch is available.
