Synopsis ========
Multiple vulnerabilities were found in the Dovecot mailserver.
Background ==========
Dovecot is an IMAP and POP3 server written with security primarily in mind.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/dovecot < 1.1.7-r1 >=3D 1.1.7-r1
Description ===========
Several vulnerabilities were found in Dovecot:
* The "k" right in the acl_plugin does not work as expected (CVE-2008-4577, CVE-2008-4578)
* The dovecot.conf is world-readable, providing improper protection for the ssl_key_password setting (CVE-2008-4870)
* A permanent Denial of Service with broken mail headers is possible (CVE-2008-4907)
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Dovecot users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-mail/dovecot-1.1.7-r1"
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".
