There is a bug in the dovecot-managesieve that allows virtual users
to get read/write access to the other's sieve files in some curcumstances:


Look at http://www.dovecot.org/list/dovecot/2008-November/035259.html

PR ports/129028 mentions the security vulnerability (that was eliminated
by that PR), but does not add a new VuXML entry.


The following VuXML entry should be evaluated and added:
--- vuln.xml begins here ---
  <vuln vid="unknown">
    <topic>dovecot-managesieve -- unallowed read/write access to the sieve scripts by virtual users</topic>
      <body xmlns="http://www.w3.org/1999/xhtml">
	<p>Stephan Bosch, maintainer of dovecot-managesieve, reports:</p>
	<blockquote cite="http://www.dovecot.org/list/dovecot/2008-November/035259.html">
	<p>&hellip;clever virtual users that know the directory
	structure of the server can read and edit script files of
	other virtual users with the same system uid.</p>
--- vuln.xml ends here ---

I had marked port versions '>=0.11.0<0.11.1' to be affected too, because
these upstream versions are affected.  There are no such port versions
in the official FreeBSD ports tree.
