==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.04
- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)

Summary:
Several security issues were fixed in QEMU.
Software Description:
- qemu: Machine emulator and virtualizer
Details:
It was discovered that QEMU did not properly manage the guest drivers when
shared buffers are not allocated. A malicious guest driver could use this
issue to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 20.04 LTS, Ubuntu
22.04 LTS and Ubuntu 22.10. (CVE-2022-1050)
It was discovered that QEMU did not properly check the size of the
structure pointed to by the guest physical address pqxl. A malicious guest
attacker could use this issue to cause QEMU to crash, resulting in a denial
of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS,
Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 22.10.
(CVE-2022-4144)
It was discovered that QEMU did not properly manage memory in the ACPI
Error Record Serialization Table (ERST) device. A malicious guest attacker
could use this issue to cause QEMU to crash, resulting in a denial of
service. This issue only affected Ubuntu 22.10. (CVE-2022-4172)
It was discovered that QEMU did not properly manage memory when DMA memory
writes happen repeatedly in the lsi53c895a device. A malicious guest
attacker could use this issue to cause QEMU to crash, resulting in a denial
of service. (CVE-2023-0330)
