linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp,
linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
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-azure-4.15: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe: Linux hardware enablement (HWE) kernel
Details:
It was discovered that a race condition existed in the ATM (Asynchronous
Transfer Mode) 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-2023-51780)
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)
It was discovered that the netfilter connection tracker for netlink in the
Linux kernel did not properly perform reference counting in some error
conditions. A local attacker could possibly use this to cause a denial of
service (memory exhaustion). (CVE-2023-7192)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:

linux-image-virtual-hwe-16.04 4.15.0.222.6
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.

- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in Firefox.
Software Description:
- firefox: Mozilla Open Source web browser
Details:
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2024-1547,
CVE-2024-1548, CVE-2024-1549, CVE-2024-1550, CVE-2024-1553, CVE-2024-1554,
CVE-2024-1555, CVE-2024-1557)
Alfred Peters discovered that Firefox did not properly manage memory when
storing and re-accessing data on a networking channel. An attacker could
potentially exploit this issue to cause a denial of service.
(CVE-2024-1546)
Johan Carlsson discovered that Firefox incorrectly handled Set-Cookie
response headers in multipart HTTP responses. An attacker could
potentially exploit this issue to inject arbitrary cookie values.
(CVE-2024-1551)
Gary Kwong discovered that Firefox incorrectly generated codes on 32-bit
ARM devices, which could lead to unexpected numeric conversions or
undefined behaviour. An attacker could possibly use this issue to cause a
denial of service. (CVE-2024-1552)
Ronald Crane discovered that Firefox did not properly manage memory when
accessing the built-in profiler. An attacker could potentially exploit
this issue to cause a denial of service. (CVE-2024-1556)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS:
firefox 123.0+build3-0ubuntu0.20.04.1
After a standard system update you need to restart Firefox to make all the
necessary changes.

in the Linux kernel did not properly validate certain server commands
fields, leading to an out-of-bounds read vulnerability. An attacker could
use this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2024-0565)
