    <p>
    Netpbm is a package of 220 graphics programs and a programming
    libraries, including pstopnm. pstopnm is a tool which converts
    PostScript files to PNM image files.
    </p>
  </background>
  <description>
    <p>
    Max Vozeler reported that pstopnm calls the GhostScript interpreter on
    untrusted PostScript files without specifying the -dSAFER option, to
    convert a PostScript file into a PBM, PGM, or PNM file.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious PostScript file and entice a user
    to run pstopnm on it, resulting in the execution of arbitrary commands
    with the permissions of the user running pstopnm.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Netpbm users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose media-libs/netpbm</code>
  </resolution>
