Advisory ID:       RHSA-2013:0515-02
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-0515.html

CVE Names:         CVE-2012-1182 
=====================================================================

1. Summary:

Updated openchange packages that fix one security issue, several bugs, and
add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

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

The openchange packages provide libraries to access Microsoft Exchange
servers using native protocols. Evolution-MAPI uses these libraries to
integrate the Evolution PIM application with Microsoft Exchange servers.

A flaw was found in the Samba suite's Perl-based DCE/RPC IDL (PIDL)
compiler. As OpenChange uses code generated by PIDL, this could have
resulted in buffer overflows in the way OpenChange handles RPC calls. With
this update, the code has been generated with an updated version of PIDL to
correct this issue. (CVE-2012-1182)

The openchange packages have been upgraded to upstream version 1.0, which
provides a number of bug fixes and enhancements over the previous version,
including support for the rebased samba4 packages and several API changes.
(BZ#767672, BZ#767678)

This update also fixes the following bugs:

* When the user tried to modify a meeting with one required attendee and
himself as the organizer, a segmentation fault occurred in the memcpy()
function. Consequently, the evolution-data-server application terminated
unexpectedly with a segmentation fault. This bug has been fixed and
evolution-data-server no longer crashes in the described scenario.
(BZ#680061)

* Prior to this update, OpenChange 1.0 was unable to send messages with
a large message body or with extensive attachment. This was caused by minor
issues in OpenChange's exchange.idl definitions. This bug has been fixed
and OpenChange now sends extensive messages without complications.
(BZ#870405)

All users of openchange are advised to upgrade to these updated packages,
which fix these issues and add these enhancements.

4. Solution:

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