  <title>Xpdf: Untrusted search path</title>

    A vulnerability in Xpdf might allow local attackers to execute arbitrary
    code.

    <p>
    Xpdf is a PDF file viewer that runs under the X Window System.

  <description>
    <p>
    Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc"
    file from the current working directory if it cannot find a ".xpdfrc"
    file in the user's home directory. This is caused by a missing
    definition of the SYSTEM_XPDFRC macro when compiling a repackaged
    version of Xpdf.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could entice a user to run "xpdf" from a directory
    containing a specially crafted "xpdfrc" file, resulting in the
    execution of arbitrary code when attempting to, e.g., print a file.
    </p>
  </impact>
  <workaround>
    <p>
    Do not run Xpdf from untrusted working directories.
    </p>
  </workaround>
  <resolution>
    <p>
    All Xpdf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/xpdf-3.02-r2"</code>
