| Description: | KVM (Kernel-based Virtual Machine) is a full virtualization solution forLinux on AMD64 and Intel 64 systems. The qemu-kvm package provides theuser-space component for running virtual machines using KVM.An information leak flaw was found in the way QEMU's VGA emulator accessedframe buffer memory for high resolution displays. A privileged guest usercould use this flaw to leak memory contents of the host to the guest bysetting the display to use a high resolution in the guest. (CVE-2014-3615)This issue was discovered by Laszlo Ersek of Red Hat.This update also fixes the following bug:* This update fixes a regression in the scsi_block_new_request() function,which caused all read requests to through SG_IO if the host cache was notused. (BZ#1141189)All qemu-kvm users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing thisupdate, shut down all running virtual machines. Once all virtual machineshave shut down, start them again for this update to take effect. |
