RHEL 6 : rhevm-spice-client (RHSA-2015:0698) (POODLE)

Synopsis :

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

Description :

Updated rhevm-spice-client packages that fix multiple security issues,
several bugs, and add one enhancement are now available for Red Hat
Enterprise Virtualization Manager 3.

Red Hat Product Security has rated this update as having Important
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.

Red Hat Enterprise Virtualization Manager provides access to virtual
machines using SPICE. These SPICE client packages provide the SPICE
client and usbclerk service for both Windows 32-bit operating systems
and Windows 64-bit operating systems.

This update adds support for the TLS Fallback Signaling Cipher Suite
Value (TLS_FALLBACK_SCSV), which can be used to prevent protocol
downgrade attacks against applications which re-connect using a lower
SSL/TLS protocol version when the initial connection indicating the
highest supported protocol version fails.

This can prevent a forceful downgrade of the communication to SSL 3.0.
The SSL 3.0 protocol was found to be vulnerable to the padding oracle
attack when using block cipher suites in cipher block chaining (CBC)
mode. This issue is identified as CVE-2014-3566, and also known under
the alias POODLE. This SSL 3.0 protocol flaw will not be addressed in
a future update; it is recommended that users configure their
applications to require at least TLS protocol version 1.0 for secure
communication.

For additional information about this flaw, see the Knowledgebase
article at https://access.redhat.com/articles/1232123

Multiple flaws were found in the way JasPer decoded JPEG 2000 image
files. A specially crafted file could cause an application using
JasPer to crash or, possibly, execute arbitrary code. (CVE-2014-8138,
CVE-2014-8157, CVE-2014-8158, CVE-2014-9029, CVE-2014-8137,
CVE-2011-4516, CVE-2011-4517, CVE-2008-3520, CVE-2008-3522)

Red Hat would like to thank oCERT for reporting CVE-2014-8137,
CVE-2014-8138, CVE-2014-8157, CVE-2014-8158, CVE-2014-9029,
CVE-2011-4516, and CVE-2011-4517. oCERT acknowledges Jose Duart of the
Google Security Team as the original reporter of CVE-2014-8137 and
CVE-2014-8138; and pyddeh as the original reporter of CVE-2014-8157
and CVE-2014-8158.

The mingw-openssl and mingw-jasper packages have been upgraded to the
latest upstream version, which provides a number of bug fixes and
enhancements over the previous version. (BZ#1187585)

This update also fixes the following bugs :

* Previously, a guest system installed with tools incorrectly always
started in full screen mode, even when the 'Open in Full Screen'
option was unchecked in console options. Now, when connecting in
window mode with the option unchecked, the guest system starts in a
window as expected. (BZ#1172126)

* Prior to this update, copying and pasting of images from the client
to the guest did not work when spice-gtk was built from upstream. Now,
images can be copied and pasted without problems. (BZ#1187270)

In addition, this update adds the following enhancement :

* Administrators now have the option of automatic multiuser
installation of virt-viewer onto many client workstations.
(BZ#1187272)

All rhevm-spice-client users are advised to upgrade to these updated
packages, which correct these issues and add these enhancement.
