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):
* QEMU: slirp: heap buffer overflow while reassembling fragmented datagrams (CVE-2018-11806)
* QEMU: slirp: heap buffer overflow in tcp_emu() (CVE-2019-6778)
* QEMU: ne2000: integer overflow leads to buffer overflow issue (CVE-2018-10839)
* QEMU: pcnet: integer overflow leads to buffer overflow (CVE-2018-17962)
* QEMU: qxl: null pointer dereference while releasing spice resources (CVE-2019-12155)

Summary
Red Hat Security Advisory: qemu-kvm security and bug fix update
Notes
Topic
An update for qemu-kvm is now available for Red Hat Enterprise Linux 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.
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):
* QEMU: slirp: heap buffer overflow while reassembling fragmented datagrams (CVE-2018-11806)
* QEMU: i386: multiboot OOB access while loading kernel image (CVE-2018-7550)
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 Jskz - Zero Day Initiative (trendmicro.com) for reporting CVE-2018-11806 and Cyrille Chatras (Orange.com) and CERT-CC (Orange.com) for reporting CVE-2018-7550.
Bug Fix(es):
* Previously, live migrating a Windows guest in some cases caused the guest to become unresponsive. This update ensures that Real-time Clock (RTC) interrupts are not missed, which prevents the problem from occurring. (BZ#1596302)

Summary
Red Hat Security Advisory: qemu-kvm-ma security update
Notes
Topic
An update for qemu-kvm-ma is now available for Red Hat Enterprise Linux 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.
Details
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-ma packages provide the user-space component for running virtual machines that use KVM on the IBM z Systems, IBM Power, and 64-bit ARM architectures.
Security Fix(es):
* QEMU: slirp: heap buffer overflow while reassembling fragmented datagrams (CVE-2018-11806)
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 Jskz - Zero Day Initiative (trendmicro.com) for reporting this issue.
