Dovecot is an IMAP and POP3 server written with security primarily in
|
|
mind.

<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 ">=net-mail/dovecot-1.1.7-r1"</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>
