  <background>
    <p>
    Perl is a cross platform programming language. The DBI is the standard
    database interface module for Perl.
    </p>

  <description>
    <p>
    Javier Fernandez-Sanguino Pena discovered that the DBI library creates
    temporary files in an insecure, predictable way (CAN-2005-0077). Paul
    Szabo found out that "File::Path::rmtree" is vulnerable to various race
    conditions (CAN-2004-0452, CAN-2005-0448).
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create symbolic links in the temporary files
    directory that point to a valid file somewhere on the filesystem. When
    the DBI library or File::Path::rmtree is executed, this could be used
    to overwrite or remove files with the rights of the user calling these
    functions.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Perl users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose dev-lang/perl</code>
    <p>
    All DBI library users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose dev-perl/DBI</code>
