    <p>
    Mod_perl is an Apache module that embeds the Perl interpreter within
    the server, allowing Perl-based web-applications to be created.

  <description>
    <p>
    Alex Solvey discovered that the "path_info" variable used in file
    RegistryCooker.pm (mod_perl 2.x) or file PerlRun.pm (mod_perl 1.x), is
    not properly escaped before being processed.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send a specially crafted URL to the vulnerable
    server, possibly resulting in a massive resource consumption.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All mod_perl 1.x users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-apache/mod_perl-1.30"</code>
    <p>
    All mod_perl 2.x users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-apache/mod_perl-2.0.3-r1"</code>
