CVE-2020-11947 [LOW] QEMU regression
Title: QEMU regression
Summary: USN-8412-1 introduced a regression in QEMU
USN-8412-1 fixed vulnerabilities QEMU. On Ubuntu 20.04 LTS, the fix for
CVE-2024-4467 was incomplete and prevented the creation of boot volumes
from qcow2 images. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Felipe Franciosi, Raphael Norwitz, and Peter Turschmid discovered that the
iSCSI block driver in QEMU incorrectly handled certain responses from an
iSCSI server. A remote attacker could possibly use this issue to cause
QEMU to crash, resulting in a denial of service, or possibly execute
arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2020-1711)

CVE-2020-25084 [LOW] CWE-416 QEMU: usb: use-after-free issue while setting up packet
QEMU: usb: use-after-free issue while setting up packet
QEMU 5.0.0 has a use-after-free in hw/usb/hcd-xhci.c because the usb_packet_map return value is not checked.
A use-after-free flaw was found in the USB(xHCI/eHCI) controller emulators of QEMU. This flaw occurs while setting up the USB packet as a usb_packet_map() routine and returns an error that was not checked. This flaw allows a guest user or process to crash the QEMU process, resulting in a denial of service.
Statement: In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP qemu-kvm-rhev package.
