Vulnerability Information

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.

How to Run

Here is how to run the RHEL 6 : openchange (RHSA-2013:0515) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Red Hat Local Security Checks plugin family.
On the right side table select RHEL 6 : openchange (RHSA-2013:0515) plugin ID 64763.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl redhat-RHSA-2013-0515.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2013-0515.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - redhat-RHSA-2013-0515.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state redhat-RHSA-2013-0515.nasl -t <IP/HOST>

Go back to menu.
