    <p>
    pstotext is a program that works with GhostScript to extract plain text
    from PostScript and PDF files.
    </p>
  </background>
  <description>
    <p>
    Max Vozeler reported that pstotext calls the GhostScript interpreter on
    untrusted PostScript files without specifying the -dSAFER option.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious PostScript file and entice a user
    to run pstotext on it, resulting in the execution of arbitrary commands
    with the permissions of the user running pstotext.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All pstotext users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-text/pstotext-1.8g-r1&quot;</code>
  </resolution>
