Summary
Ziming Zhang and VictorV discovered that the QEMU SLiRP networking
implementation incorrectly handled replying to certain ICMP echo requests.
An attacker inside a guest could possibly use this issue to leak host
memory to obtain sensitive information. This issue only affected Ubuntu
18.04 LTS. (CVE-2020-10756)
Eric Blake and Xueqiang Wei discovered that the QEMU NDB implementation
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause QEMU to crash, resulting in a denial of service. This
issue only affected Ubuntu 20.04 LTS. (CVE-2020-10761)
Ziming Zhang discovered that the QEMU SM501 graphics driver incorrectly
handled certain operations. An attacker inside a guest could use this issue
to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2020-12829)
It was discovered that the QEMU SD memory card implementation incorrectly
handled certain memory operations. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. (CVE-2020-13253)
Ren Ding and Hanqing Zhao discovered that the QEMU ES1370 audio driver
incorrectly handled certain invalid frame counts. An attacker inside a
guest could possibly use this issue to cause QEMU to crash, resulting in a
denial of service. (CVE-2020-13361)
Ren Ding and Hanqing Zhao discovered that the QEMU MegaRAID SAS SCSI driver
incorrectly handled certain memory operations. An attacker inside a guest
could possibly use this issue to cause QEMU to crash, resulting in a denial
of service. (CVE-2020-13362)
Alexander Bulekov discovered that QEMU MegaRAID SAS SCSI driver incorrectly
handled certain memory space operations. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. (CVE-2020-13659)
Ren Ding, Hanqing Zhao, Alexander Bulekov, and Anatoly Trosinenko
discovered that the QEMU incorrectly handled certain msi-x mmio operations.
An attacker inside a guest could possibly use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2020-13754)
It was discovered that QEMU incorrectly handled certain memory copy
operations when loading ROM contents. If a user were tricked into running
an untrusted kernel image, a remote attacker could possibly use this issue
to run arbitrary code. This issue only affected Ubuntu 16.04 LTS and Ubuntu
18.04 LTS. (CVE-2020-13765)
Ren Ding, Hanqing Zhao, and Yi Ren discovered that the QEMU ATI video
driver incorrectly handled certain index values. An attacker inside a guest
could possibly use this issue to cause QEMU to crash, resulting in a denial
of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-13800)
Ziming Zhang discovered that the QEMU OSS audio driver incorrectly handled
certain operations. An attacker inside a guest could possibly use this
issue to cause QEMU to crash, resulting in a denial of service. This issue
only affected Ubuntu 20.04 LTS. (CVE-2020-14415)
Ziming Zhang discovered that the QEMU XGMAC Ethernet controller incorrectly
handled packet transmission. An attacker inside a guest could use this
issue to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2020-15863)
Ziming Zhang discovered that the QEMU e1000e Ethernet controller
incorrectly handled packet processing. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
(CVE-2020-16092)
