Default Moderate: dovecot security and enhancement update

-----BEGIN PGP SIGNED MESSAGE-----

================================================== ===================
Red Hat Security Advisory

Synopsis: Moderate: dovecot security and enhancement update
Advisory ID: RHSA-2011:0600-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0600.html
Issue date: 2011-05-19
CVE Names: CVE-2010-3707 CVE-2010-3780
================================================== ===================

1. Summary:

Updated dovecot packages that fix two security issues and add one
enhancement are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

3. Description:

Dovecot is an IMAP server for Linux, UNIX, and similar operating systems,
primarily written with security in mind.

A flaw was found in the way Dovecot handled SIGCHLD signals. If a large
amount of IMAP or POP3 session disconnects caused the Dovecot master
process to receive these signals rapidly, it could cause the master process
to crash. (CVE-2010-3780)

A flaw was found in the way Dovecot processed multiple Access Control Lists
(ACL) defined for a mailbox. In some cases, Dovecot could fail to apply the
more specific ACL entry, possibly resulting in more access being granted to
the user than intended. (CVE-2010-3707)

This update also adds the following enhancement:

* This erratum upgrades Dovecot to upstream version 2.0.9, providing
multiple fixes for the "dsync" utility and improving overall performance.
Refer to the "/usr/share/doc/dovecot-2.0.9/ChangeLog" file after installing
this update for further information about the changes. (BZ#637056)

Users of dovecot are advised to upgrade to these updated packages, which
resolve these issues and add this enhancement. After installing the updated
packages, the dovecot service will be restarted automatically.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

637056 - rebase dovecot to 2.0 final
640410 - CVE-2010-3707 Dovecot: Failed to properly update ACL cache, when multiple rules defined rights for one subject
641276 - CVE-2010-3780 Dovecot: Busy master process, receiving a lot of SIGCHLD signals rapidly while logging, could die
