  - The LockServer function in os/utils.c in X.Org xserver

    existence of arbitrary files via a symlink attack on a
    temporary lock file, which is handled differently if the
    file exists. (CVE-2011-4028)

  - 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. (CVE-2011-4029)"
