CVE-2011-4029 low priority: Debian including 1 source packages (xorg-server), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file.
