  <title>X.org and some X.org libraries: Local privilege escalations</title>
  <synopsis>
    X.org, libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm are vulnerable
    to local privilege escalations because of unchecked setuid() calls.

    <p>
    X.org is an implementation of the X Window System.
    </p>
  </background>
  <description>
    <p>
    Several X.org libraries and X.org itself contain system calls to
    set*uid() functions, without checking their result.
    </p>
  </description>
  <impact type="high">
    <p>
    Local users could deliberately exceed their assigned resource limits
    and elevate their privileges after an unsuccessful set*uid() system
    call. This requires resource limits to be enabled on the machine.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
