The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.

Security readout for executives and security teams

This CVE affects the X.Org X wrapper used in Debian GNU/Linux and Ubuntu Linux. A local user could bypass intended restrictions for starting X because the wrapper incorrectly checks the user’s TTY. This is a local access-control weakness, not a remote internet-facing issue in the supplied evidence. Exposure is most likely on legacy Debian or Ubuntu systems using the affected X.Org X wrapper, especially where non-administrative local users can log in and attempt to start X. Internet-facing services are not indicated by the sources. Treat this as a targeted local privilege or access-control concern for older Debian and Ubuntu systems, not an emergency internet-wide exposure. Prioritize patch verification on shared workstations, lab systems, and servers with local user accounts. Mitigation focus: Review Debian DSA-2364 and Ubuntu USN-1349-1 for vendor update guidance.; Apply the relevant Debian or Ubuntu security updates where affected systems remain in service.; Prioritize systems that allow interactive logins by untrusted or semi-trusted users..
