Debian Security Advisory DSA-1516-1 security@debian.org
http://www.debian.org/security/ Florian Weimer
March 14, 2008 http://www.debian.org/security/faq
- ----------------------------------------------------------------------
Package : dovecot
Vulnerability : privilege escalation
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2008-1199 CVE-2008-1218
Debian Bug : 469457
Prior to this update, the default configuration for Dovecot used by
Debian runs the server daemons with group mail privileges. This means
that users with write access to their mail directory by other means
(for example, through an SSH login) could read mailboxes owned by
other users for which they do not have direct write access
(CVE-2008-1199). In addition, an internal interpretation conflict in
password handling has been addressed proactively, even though it is
not known to be exploitable (CVE-2008-1218).
Note that applying this update requires manual action: The
configuration setting "mail_extra_groups = mail" has been replaced
with "mail_privileged_group = mail". The update will show a
configuration file conflict in /etc/dovecot/dovecot.conf. It is
recommended that you keep the currently installed configuration file,
and change the affected line. For your reference, the sample
configuration (without your local changes) will have been written to
/etc/dovecot/dovecot.conf.dpkg-new.
If your current configuration uses mail_extra_groups with a value
different from "mail", you may have to resort to the
mail_access_groups configuration directive.
For the stable distribution (etch), these problems have been fixed in
version 1.0.rc15-2etch4.
For the unstable distribution (sid), these problems have been fixed in
version 1.0.13-1.
For the old stable distribution (sarge), no updates are provided.
We recommend that you consider upgrading to the stable distribution.
Upgrade instructions

You may use an automated update by adding the resources from the
footer to the proper configuration.
