Name of the Vulnerable Software and Affected Versions lightdm versions prior to 0.9.6

Description The issue allows a local user to potentially escalate privileges by overwriting root-owned files via a symlink. This is possible because lightdm writes in .dmrc and Xauthority files using root permissions while the files are in user-controlled folders.

Recommendations For versions prior to 0.9.6, update to version 0.9.6 or later to resolve the issue.
