Summary
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.

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)

Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Virtualization 4 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
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.
The following packages have been upgraded to a later upstream version: qemu-kvm-rhev (2.10.0). (BZ#1470749)
Security Fix(es):
* Qemu: stack buffer overflow in NBD server triggered via long export name (CVE-2017-15118)
* Qemu: DoS via large option request (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)
* Qemu: memory exhaustion through framebuffer update request message in VNC server (CVE-2017-15124)
* Qemu: I/O: potential memory exhaustion via websock connection to VNC (CVE-2017-15268)
* Qemu: Out-of-bounds read in vga_draw_text routine (CVE-2018-5683)
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; Wjjzhang (Tencent.com) for reporting CVE-2017-13711; and Jiang Xin and Lin ZheCheng for reporting CVE-2018-5683. The CVE-2017-15118 and CVE-2017-15119 issues were discovered by Eric Blake (Red Hat) and the CVE-2017-15124 issue was discovered by Daniel Berrange (Red Hat).

Details
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
