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.

 

Security Fix(es):

 

* A memory allocation flaw, leading to a heap-based buffer overflow, was

found in spice's smartcard interaction, which runs under the QEMU-KVM

context on the host. A user connecting to a guest VM using spice could

potentially use this flaw to crash the QEMU-KVM process or execute

arbitrary code with the privileges of the host's QEMU-KVM process.

(CVE-2016-0749)

 

* A memory access flaw was found in the way spice handled certain guests

using crafted primary surface parameters. A user in a guest could use this

flaw to read from and write to arbitrary memory locations on the host.

(CVE-2016-2150)

 

The CVE-2016-0749 issue was discovered by Jing Zhao (Red Hat) and the

CVE-2016-2150 issue was discovered by Frediano Ziglio (Red Hat).

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

Applications acting as a SPICE server must be restarted for this update to

take effect. Note that QEMU-KVM guests providing SPICE console access must

be restarted for this update to take effect.

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

1300646 - CVE-2016-0749 spice: heap-based memory corruption within smartcard handling

1313496 - CVE-2016-2150 spice: Host memory access from guest with invalid primary surface parameters
