Detail
Problem Description: Updated qemu-kvm packages that fix one security issue are now available for Red Hat Enterprise Linux 6. 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: Red Hat Enterprise Linux Desktop (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - x86_64 Red Hat Enterprise Linux Workstation (v. 6) - x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running virtual machines using KVM. A flaw was found in the way qemu-kvm handled VSC_ATR messages when a guest was configured for a CCID (Chip/Smart Card Interface Devices) USB smart card reader in passthrough mode. An attacker able to connect to the port on the host being used for such a device could use this flaw to crash the qemu-kvm process on the host or, possibly, escalate their privileges on the host. (CVE-2011-4111) All users of qemu-kvm should upgrade to these updated packages, which contain a backported patch to resolve this issue. 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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 751310 - CVE-2011-4111 qemu: ccid: buffer overflow in handling of VSC_ATR message |
