Ubuntu Security Notice USN-6609-1

Ubuntu Security Notice USN-6609-1
Posted Jan 26, 2024
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 6609-1 - Lin Ma discovered that the netfilter subsystem in the Linux kernel did not properly validate network family support while creating a new netfilter table. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information.

==========================================================================

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke: Linux kernel for Google Container Engine (GKE) systems
- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-kvm: Linux kernel for cloud environments
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gkeop-5.15: Linux kernel for Google Container Engine (GKE) systems
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel
- linux-ibm-5.15: Linux kernel for IBM cloud systems
- linux-lowlatency-hwe-5.15: Linux low latency kernel

Details:

Lin Ma discovered that the netfilter subsystem in the Linux kernel did not
properly validate network family support while creating a new netfilter
table. A local attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6040)

It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly validate the server frame size in certain
situation, leading to an out-of-bounds read vulnerability. An attacker
could use this to construct a malicious CIFS image that, when operated on,
could cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2023-6606)

Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did
not properly handle inactive elements in its PIPAPO data structure, 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-2023-6817)

Budimir Markovic, Lucas De Marchi, and Pengfei Xu discovered that the perf
subsystem in the Linux kernel did not properly validate all event sizes
when attaching new events, leading to an out-of-bounds write vulnerability.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2023-6931)

It was discovered that the IGMP protocol implementation in the Linux kernel
contained a race condition, 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-2023-6932)

Kevin Rich discovered that the netfilter subsystem in the Linux kernel did
not properly check deactivated elements in certain situations, 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-2024-0193)

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.
