"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.

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."
