NewStart CGSL MAIN 6.06 : sddm Vulnerability (NS-SA-2025-0233)

high Nessus Plugin ID 266240

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.06, has sddm packages installed that are affected by a vulnerability:

 - daemon/Greeter.cpp in sddm before 0.13.0 does not properly disable the KDE crash handler, which allows local users to gain privileges by crashing a greeter when using certain themes, as demonstrated by the plasma-workspace breeze theme. (CVE-2015-0856)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
