Summary
Red Hat Security Advisory: qemu-kvm security update
Notes
Topic
An update for qemu-kvm is now available for Red Hat Enterprise Linux 6.
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.
Details
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.
Security Fix(es):
* An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639)
Note: This is the qemu-kvm side of the CVE-2018-3639 mitigation.
* QEMU: cirrus: OOB access when updating VGA display (CVE-2018-7858)
* QEMU: vga: OOB read access during display update (CVE-2017-13672)
* Qemu: Out-of-bounds read in vga_draw_text routine (CVE-2018-5683)

The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es):\n\n* An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load \u0026 Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor\u0027s data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639)\n\nNote: This is the qemu-kvm side of the CVE-2018-3639 mitigation.\n\n* QEMU: cirrus: OOB access when updating VGA display (CVE-2018-7858)\n\n* QEMU: vga: OOB read access during display update (CVE-2017-13672)\n\n* Qemu: Out-of-bounds read in vga_draw_text routine (CVE-2018-5683)\n\nFor more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.\n\nRed Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting CVE-2018-3639; Ross Lagerwall (Citrix.com) for reporting CVE-2018-7858; David Buchanan for reporting CVE-2017-13672; and Jiang Xin and Lin ZheCheng for reporting CVE-2018-5683.", "title": "Details" }, { "category": "legal_disclaimer", "text": "This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

execution of Load \u0026 Store instructions (a commonly used performance optimization).

Summary
Red Hat Security Advisory: qemu-kvm-rhev security and bug fix update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton), Red Hat OpenStack Platform 11.0 (Ocata), Red Hat OpenStack Platform 12.0 (Pike), Red Hat OpenStack Platform 8.0 (Liberty), and Red Hat OpenStack Platform 9.0 (Mitaka).
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
Details
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):
* The Network Block Device (NBD) server in Quick Emulator (QEMU), is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS. (CVE-2017-15119)
* Qemu: vga: OOB read access during display update (CVE-2017-13672)
* Qemu: vga: reachable assert failure during display update (CVE-2017-13673)
* Qemu: Slirp: use-after-free when sending response (CVE-2017-13711)
* VNC server implementation in Quick Emulator (QEMU) was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host. (CVE-2017-15124)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank David Buchanan for reporting CVE-2017-13672 and CVE-2017-13673 and Wjjzhang (Tencent.com) for reporting CVE-2017-13711. The CVE-2017-15119 issue was discovered by Eric Blake (Red Hat) and the CVE-2017-15124 issue was discovered by Daniel Berrange (Red Hat).
