The Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060317, and Solaris 8 through 10 before 20061006, allows local users to overwrite arbitrary files, or read another user's Xsession errors file, via a symlink attack on a /tmp/xses-$USER file.

Security readout for executives and security teams

This is an old local-user flaw in the xdm Xsession script. On affected NetBSD, X.Org, and Solaris systems, a local account could abuse temporary Xsession error-file handling to overwrite files or read another user's session error file. Exposure is likely limited to legacy Unix systems using affected xdm/Xsession implementations. Modern systems not running xdm, or systems patched after the cited vendor dates, are less likely exposed. Confirm package provenance and vendor backports. Treat this as a legacy-platform hygiene issue. It is not evidenced as internet-exploited, but systems with shared local access and old graphical login stacks should be prioritized for patch verification or retirement. Mitigation focus: Upgrade affected NetBSD, X.Org, and Solaris components beyond the cited vulnerable dates.; Check vendor advisories for backported fixes on supported legacy platforms.; Disable or replace xdm where it is unnecessary on legacy systems..
