Detail
The ACL plugin in dovecot prior to version 1.1.4 treated negative access rights as though they were positive access rights, which allowed attackers to bypass intended access restrictions (CVE-2008-4577). The ACL plugin in dovecot prior to version 1.1.6 allowed attackers to bypass intended access restrictions by using the 'k' right to create unauthorized 'parent/child/child' mailboxes (CVE-2008-4578). In addition, two bugs were discovered in the dovecot package shipped with Mandriva Linux 2009.0. The default permissions on the dovecot.conf configuration file were too restrictive, which prevents the use of dovecot's 'deliver' command as a non-root user. Secondly, dovecot should not start until after ntpd, if ntpd is active, because if ntpd corrects the time backwards while dovecot is running, dovecot will quit automatically, with the log message 'Time just moved backwards by X seconds. This might cause a lot of problems, so I'll just kill myself now.' The update resolves both these problems. The default permissions on dovecot.conf now allow the 'deliver' command to read the file. Note that if you edited dovecot.conf at all prior to installing the update, the new permissions may not be applied. If you find the 'deliver' command still does not work following the update, please run these commands as root: # chmod 0640 /etc/dovecot.conf # chown root:mail /etc/dovecot.conf Dovecot's initialization script now configures it to start after the ntpd service, to ensure ntpd resetting the clock does not interfere with Dovecot operation. This package corrects the above-noted bugs and security issues by upgrading to the latest dovecot 1.1.6, which also provides additional bug fixes. |
