<background>
<p>
Dovecot is an IMAP and POP3 server written with security primarily in
mind.
</p>
</background>
<description>
<p>
Several vulnerabilities were found in Dovecot:
</p>
<ul>
<li>The "k"
right in the acl_plugin does not work as expected (CVE-2008-4577,
CVE-2008-4578)</li>
<li>The dovecot.conf is world-readable, providing
improper protection for the ssl_key_password setting
(CVE-2008-4870)</li>
<li>A permanent Denial of Service with broken mail
headers is possible (CVE-2008-4907)</li>
</ul>
</description>
<impact type="normal">
<p>
These vulnerabilities might allow a remote attacker to cause a Denial
of Service, to circumvent security restrictions or allow local
attackers to disclose the passphrase of the SSL private key.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Dovecot users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-mail/dovecot-1.1.7-r1&quot;</code>
<p>
Users should be aware that dovecot.conf will still be world-readable
after the update. If employing ssl_key_password, it should not be used
in dovecot.conf but in a separate file which should be included with
"include_try".
</p>
