-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: qemu-kvm-rhev security and bug fix update Advisory ID: RHSA-2017:1682-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2017:1682 Issue date: 2017-07-05 CVE Names: CVE-2017-9524 ===================================================================== 1. Summary: An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor and Agents for RHEL-7 and RHEV 4.X RHEV-H and Agents for RHEL-7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Managment Agent for RHEL 7 Hosts - ppc64le, x86_64 RHEV-H and VDSM for 7 Hosts - ppc64le, x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. Security Fix(es): * Quick Emulator (QEMU) built with Network Block Device (NBD) Server support was vulnerable to a null-pointer dereference issue. The flaw could occur when releasing a client, which was not initialized due to failed negotiation. A remote user or process could exploit this flaw to crash the qemu-nbd server (denial of service). (CVE-2017-9524) Bug Fix(es): * Previously, when the data plane was in use, changing the target image of a virtual SCSI CD device caused the guest to terminate unexpectedly with a core dump. With this update, the virtio-scsi bus rejects SCSI CDs when the data plane is active, which prevents the crash from occurring. Note that this is a temporary solution, and a full fix to make the data plane and SCSI CD compatible will be provided in the future. (BZ#1461837) 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 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. 5. Bugs fixed (https://bugzilla.redhat.com/): 1460170 - CVE-2017-9524 Qemu: nbd: segmentation fault due to client non-negotiation 1461837 - Core dump when use "data-plane" and execute change cd 6.
