GLSA-200812-16 : Dovecot: Multiple vulnerabilities

Medium Nessus Plugin ID 35108


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200812-16 (Dovecot: Multiple vulnerabilities)

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.


All Dovecot users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-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'.
