Name of the Vulnerable Software and Affected Versions sddm versions prior to 0.13.0

Description The issue is related to the daemon/Greeter.cpp in sddm, where it does not properly disable the KDE crash handler. This allows local users to gain privileges by crashing a greeter when using certain themes. An example of such a theme is the plasma-workspace breeze theme.

Recommendations For versions prior to 0.13.0, update to version 0.13.0 or later to resolve the issue. As a temporary workaround, consider avoiding the use of themes that may trigger the crash handler, such as the plasma-workspace breeze theme, until the update is applied.
