Synopsis: Moderate: openchange security, bug fix and enhancement update
Issue Date: 2013-02-21
CVE Numbers: CVE-2012-1182
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.
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.
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.
* 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.
