Ubuntu 20.04 LTS / 22.04 LTS : QEMU regression (USN-6567-2)

info Nessus Plugin ID 200171

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6567-2 advisory.

 USN-6567-1 fixed vulnerabilities QEMU. The fix for CVE-2023-2861 was too restrictive and introduced a behaviour change leading to a regression in certain environments. This update fixes the problem.

 Original advisory details:

 Gaoning Pan and Xingwei Li discovered that QEMU incorrectly handled the

 USB xHCI controller device. A privileged guest attacker could possibly use

 this issue to cause QEMU to crash, leading to a denial of service. This

 issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2020-14394)

 It was discovered that QEMU incorrectly handled the TCG Accelerator. A

 local attacker could use this issue to cause QEMU to crash, leading to a

 denial of service, or possibly execute arbitrary code and esclate

 privileges. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-24165)

 It was discovered that QEMU incorrectly handled the Intel HD audio device.

 A malicious guest attacker could use this issue to cause QEMU to crash,

 leading to a denial of service. This issue only affected Ubuntu 22.04 LTS.

 (CVE-2021-3611)

 It was discovered that QEMU incorrectly handled the ATI VGA device. A

 malicious guest attacker could use this issue to cause QEMU to crash,

 leading to a denial of service. This issue only affected Ubuntu 20.04 LTS.

 (CVE-2021-3638)

 It was discovered that QEMU incorrectly handled the VMWare paravirtual RDMA

 device. A malicious guest attacker could use this issue to cause QEMU to

 crash, leading to a denial of service. (CVE-2023-1544)

 It was discovered that QEMU incorrectly handled the 9p passthrough

 filesystem. A malicious guest attacker could possibly use this issue to

 open special files and escape the exported 9p tree. This issue only

 affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04.

 (CVE-2023-2861)

 It was discovered that QEMU incorrectly handled the virtual crypto device.

 A malicious guest attacker could use this issue to cause QEMU to crash,

 leading to a denial of service, or possibly execute arbitrary code. This

 issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04.

 (CVE-2023-3180)

 It was discovered that QEMU incorrectly handled the built-in VNC server.

 A remote authenticated attacker could possibly use this issue to cause QEMU

 to stop responding, resulting in a denial of service. This issue only

 affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-3255)

 It was discovered that QEMU incorrectly handled net device hot-unplugging.

 A malicious guest attacker could use this issue to cause QEMU to crash,

 leading to a denial of service. This issue only affected Ubuntu 22.04 LTS

 and Ubuntu 23.04. (CVE-2023-3301)

 It was discovered that QEMU incorrectly handled the built-in VNC server.

 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, Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-3354)

 It was discovered that QEMU incorrectly handled NVME devices. A malicious

 guest attacker could use this issue to cause QEMU to crash, leading to a

 denial of service. This issue only affected Ubuntu 23.10. (CVE-2023-40360)

 It was discovered that QEMU incorrectly handled NVME devices. A malicious

 guest attacker could use this issue to cause QEMU to crash, leading to a

 denial of service, or possibly obtain sensitive information. This issue

 only affected Ubuntu 23.10. (CVE-2023-4135)

 It was discovered that QEMU incorrectly handled SCSI devices. A malicious

 guest attacker could use this issue to cause QEMU to crash, leading to a

 denial of service. This issue only affected Ubuntu 23.04 and Ubuntu 23.10.

 (CVE-2023-42467)

 It was discovered that QEMU incorrectly handled certain disk offsets. A

 malicious guest attacker could possibly use this issue to gain control of

 the host in certain nested virtualization scenarios. (CVE-2023-5088)
