    <p>
    LibAST is a utility library that was originally intended to accompany
    Eterm, but may be used by various other applications.

  <description>
    <p>
    Michael Jennings discovered an exploitable buffer overflow in the
    configuration engine of LibAST.
    </p>
  </description>
  <impact type="high">
    <p>
    The vulnerability can be exploited to gain escalated privileges if the
    application using LibAST is setuid/setgid and passes a specifically
    crafted filename to LibAST's configuration engine.
    </p>
  </impact>
  <workaround>
    <p>
    Identify all applications linking against LibAST and verify they are
    not setuid/setgid.
    </p>
  </workaround>
  <resolution>
    <p>
    All users should upgrade to the latest version and run revdep-rebuild:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=x11-libs/libast-0.7"
    # revdep-rebuild</code>
  </resolution>
