  <title>libgtop: Privilege escalation</title>
  <synopsis>
    libgtop improperly handles filenames, possibly allowing for the execution
    of arbitrary code.

  <background>
    <p>
    libgtop facilitates the libgtop_daemon, which is used by GNOME to
    obtain information about remote systems.

  <description>
    <p>
    Liu Qishuai discovered that glibtop_get_proc_map_s() in
    sysdeps/linux/procmap.c does not properly allocate memory for storing a
    filename, allowing certain filenames to cause the buffer to overflow on
    the stack.
    </p>
  </description>
  <impact type="normal">
    <p>
    By tricking a victim into executing an application that uses the
    libgtop library (e.g. libgtop_daemon or gnome-system-monitor), a local
    attacker could specify a specially crafted filename to be used by
    libgtop causing a buffer overflow and possibly execute arbitrary code
    with the rights of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libgtop users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=gnome-base/libgtop-2.14.6"</code>
