Security readout for executives and security teams
CVE-2011-4105 is a LightDM flaw where a local user could abuse handling of ~/.Xauthority to make LightDM change ownership of files it should not touch. This matters mainly on systems where users have local login access and LightDM versions before 1.0.6 are still present. Exposure is likely limited to legacy Linux systems running LightDM earlier than 1.0.6, especially desktops, kiosks, or shared hosts with local user access. The provided sources do not identify every affected distribution or package build. Treat as a legacy local-privilege risk. Prioritize remediation where LightDM is used on shared, kiosk, lab, or multi-user systems. Internet-facing urgency is lower based on the provided evidence. Mitigation focus: Upgrade LightDM to 1.0.6 or a vendor-fixed package.; Apply Ubuntu USN-1262-1 updates where applicable.; Inventory legacy Linux systems using LightDM..
