debian/guest-account in Light Display Manager (lightdm) 1.0.x before 1.0.6 and 1.1.x before 1.1.7, as used in Ubuntu Linux 11.10, allows local users to delete arbitrary files via a space in the name of a file in /tmp. NOTE: this identifier was SPLIT per ADT1/ADT2 due to different codebases and affected versions. CVE-2012-6648 has been assigned for the gdm-guest-session issue.

Security readout for executives and security teams

This is a local file-deletion flaw in legacy LightDM guest-account handling. On affected Ubuntu 11.10 systems, a local user could cause arbitrary files to be deleted by abusing filenames containing spaces in /tmp. It is not a remote compromise, but it can damage system integrity on exposed multi-user or shared desktop hosts. Exposure is most likely limited to legacy Ubuntu 11.10 or similarly packaged systems using affected LightDM guest-account code. Modern systems are unlikely to be affected unless they retain old LightDM packages or unsupported images. Treat this as a legacy platform hygiene issue, not an internet-scale emergency. Prioritize if shared Linux desktops, kiosks, or guest-session systems still exist, because local users could cause destructive file deletion. Mitigation focus: Update LightDM to a vendor-fixed version or supported distribution package.; Disable guest sessions until affected LightDM packages are remediated.; Prioritize unsupported Ubuntu 11.10 systems for retirement or isolation..
