=====================================================================
1. Summary:
Updated qspice packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
important 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:
RHEL Desktop Multi OS (v. 5 client) - x86_64
RHEL Virtualization (v. 5 server) - x86_64
Red Hat Enterprise Linux (v. 5 server) - x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - x86_64
3. Description:
The Simple Protocol for Independent Computing Environments (SPICE) is a
remote display protocol for virtual environments. SPICE users can access a
virtualized desktop or server from the local system or any system with
network access to the server. SPICE is used in Red Hat Enterprise Linux for
viewing virtualized guests running on the Kernel-based Virtual Machine
(KVM) hypervisor or on Red Hat Enterprise Virtualization Hypervisors.
A stack-based buffer overflow flaw was found in the way the
reds_handle_ticket() function in the spice-server library handled
decryption of ticket data provided by the client. A remote user able to
initiate a SPICE connection to an application acting as a SPICE server
could use this flaw to crash the application. (CVE-2013-4282)
This issue was discovered by Tomas Jamrisko of Red Hat.
All qspice users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously released errata
