Summary
Details
The imx_fec_do_tx function in hw/net/imx_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.

Details
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-10028, CVE-2016-10029)
Li Qiang discovered that QEMU incorrectly handled the 6300esb watchdog. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-10155)
Li Qiang discovered that QEMU incorrectly handled the i.MX Fast Ethernet Controller. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-7907)
It was discovered that QEMU incorrectly handled the JAZZ RC4030 device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-8667)
It was discovered that QEMU incorrectly handled the 16550A UART device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-8669)
It was discovered that QEMU incorrectly handled the shared rings when used with Xen. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. (CVE-2016-9381)
Jann Horn discovered that QEMU incorrectly handled VirtFS directory sharing. A privileged attacker inside the guest could use this issue to access files on the host file system outside of the shared directory and possibly escalate their privileges. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2016-9602)
Gerd Hoffmann discovered that QEMU incorrectly handled the Cirrus VGA device when being used with a VNC connection. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2016-9603)
It was discovered that QEMU incorrectly handled the ColdFire Fast Ethernet Controller. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-9776)
Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to leak contents of host memory. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9845, CVE-2016-9908)
Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9846, CVE-2016-9912, CVE-2017-5552, CVE-2017-5578, CVE-2017-5857)
Li Qiang discovered that QEMU incorrectly handled the USB redirector. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-9907)
Li Qiang discovered that QEMU incorrectly handled USB EHCI emulation. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-9911)
Li Qiang discovered that QEMU incorrectly handled VirtFS directory sharing. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-9913, CVE-2016-9914, CVE-2016-9915, CVE-2016-9916)
Qinghao Tang, Li Qiang, and Jiangxin discovered that QEMU incorrectly handled the Cirrus VGA device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-9921, CVE-2016-9922)
Wjjzhang and Li Qiang discovered that QEMU incorrectly handled the Cirrus VGA device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2017-2615)
It was discovered that QEMU incorrectly handled the Cirrus VGA device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2017-2620)
It was discovered that QEMU incorrectly handled VNC connections. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-2633)
Li Qiang discovered that QEMU incorrectly handled the ac97 audio device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-5525)
Li Qiang discovered that QEMU incorrectly handled the es1370 audio device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-5526)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
