The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to determine the existence of arbitrary files via a symlink attack on a temporary lock file, which is handled differently if the file exists.

Security readout for executives and security teams

CVE-2011-4028 is a local information-disclosure issue in older X.Org xserver releases. A local user could use lock-file behavior to learn whether chosen files exist. The sources do not show remote access, file-content disclosure, privilege escalation, or active exploitation. Exposure is mainly legacy Linux or Unix systems running X.Org xserver before 1.11.2, especially shared multi-user hosts with local shell access. Modern distributions are unlikely to remain affected unless frozen on old packages. Treat as low urgency unless the environment has shared local-user access on obsolete graphical Linux or Unix systems. It should be cleared through normal vulnerability hygiene and legacy-system reduction, not emergency response. Mitigation focus: Upgrade X.Org xserver to 1.11.2 or a vendor-fixed package.; Review vendor advisories for backported fixes on supported distributions.; Prioritize shared multi-user systems and legacy graphical servers..
