the corresponding update for Ubuntu 14.04 LTS.

Original advisory details:

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
memory when processing the RRChangeOutputProperty and
RRChangeProviderProperty APIs. An attacker could possibly use this issue to
cause the X Server to crash, or obtain sensitive information.
(CVE-2023-6478)

obtain sensitive information, or execute arbitrary code. (CVE-2023-6816)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
reattaching to a different master device. An attacker could use this issue
to cause the X Server to crash, leading to a denial of service, or possibly
execute arbitrary code. (CVE-2024-0229)

Olivier Fourdan and Donn Seeley discovered that the X.Org X Server
incorrectly labeled GLX PBuffers when used with SELinux. An attacker could
use this issue to cause the X Server to crash, leading to a denial of
service. (CVE-2024-0408)

Olivier Fourdan discovered that the X.Org X Server incorrectly handled
the curser code when used with SELinux. An attacker could use this issue to
cause the X Server to crash, leading to a denial of service.
(CVE-2024-0409)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
memory when processing the XISendDeviceHierarchyEvent API. An attacker
could possibly use this issue to cause the X Server to crash, or execute
arbitrary code. (CVE-2024-21885)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
devices being disabled. An attacker could possibly use this issue to cause
the X Server to crash, or execute arbitrary code. (CVE-2024-21886)

[USN-6686-2] Linux kernel vulnerabilities


==========================================================================
Ubuntu Security Notice USN-6686-2
March 13, 2024

linux-lowlatency, linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-lowlatency: Linux low latency kernel
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the
Linux kernel did not properly handle certain error conditions during device
registration. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2023-22995)

It was discovered that a race condition existed in the Cypress touchscreen
driver in the Linux kernel during device removal, leading to a use-after-
free vulnerability. A physically proximate attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-4134)

黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-46343)

It was discovered that the io_uring subsystem in the Linux kernel contained
a race condition, leading to a null pointer dereference vulnerability. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-46862)

It was discovered that a race condition existed in the Bluetooth subsystem
of the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-51779)

It was discovered that a race condition existed in the Rose X.25 protocol
implementation in the Linux kernel, leading to a use-after- free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-51782)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel
did not properly handle connect command payloads in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to expose sensitive information (kernel memory). (CVE-2023-6121)

It was discovered that the VirtIO subsystem in the Linux kernel did not
properly initialize memory in some situations. A local attacker could use
this to possibly expose sensitive information (kernel memory).
(CVE-2024-0340)

Dan Carpenter discovered that the netfilter subsystem in the Linux kernel
did not store data in properly sized memory locations. A local user could
use this to cause a denial of service (system crash). (CVE-2024-0607)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
linux-image-5.15.0-100-lowlatency 5.15.0-100.110
linux-image-5.15.0-100-lowlatency-64k 5.15.0-100.110
linux-image-5.15.0-1048-raspi 5.15.0-1048.51
linux-image-lowlatency 5.15.0.100.96
linux-image-lowlatency-64k 5.15.0.100.96
linux-image-raspi 5.15.0.1048.46
linux-image-raspi-nolpae 5.15.0.1048.46

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
