Zusammenfassung:	Check the version of qemu-guest-agent
Beschreibung:	Summary: Check the version of qemu-guest-agent Vulnerability Insight: Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM. Security Fix(es): * A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603) * An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980) * An out-of-bounds memory access issue was found in QEMU's VNC display driver support. The vulnerability could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user/process inside a guest could use this flaw to crash the QEMU process, resulting in a denial of service. (CVE-2017-2633) * An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718) Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc.) for reporting CVE-2017-7718. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory see the references. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect. Affected Software/OS: qemu-guest-agent on CentOS 6 Solution: Please Install the Updated Packages. CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
