Original advisory details:

 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)

 Ziming Zhang, Xiao Wei, Gonglei Arei and Yanyu Zhang discovered that
 QEMU incorrectly handled certain USB packets. An attacker could possibly
 use this to expose sensitive information or execute arbitrary code.
 (CVE-2020-14364)");
