Ubuntu Security Notice USN-6758-1
April 30, 2024

node-json5 vulnerability
==========================================================================

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

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

JSON5 could allow unintended access to network services or have other
unspecified impact.

Software Description:
- node-json5: JSON for the ES5 era

Details:

It was discovered that the JSON5 parse method incorrectly handled the parsing
of keys named __proto__. An attacker could possibly use this issue to pollute
the prototype of the returned object, setting arbitrary or unexpected keys, and
cause a denial of service, allow unintended access to network services or have
other unspecified impact, depending on the application's use of the module.

Update instructions:

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

Ubuntu 22.04 LTS
node-json5 2.2.0+dfsg-1ubuntu0.1~esm1
Available with Ubuntu Pro

Ubuntu 20.04 LTS
node-json5 0.5.1-3ubuntu0.1

[LSN-0103-1] Linux kernel vulnerability

Linux kernel vulnerabilities

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 22.04 LTS

Summary

Several security issues were fixed in the kernel.

Software Description

- linux - Linux kernel
- linux-aws - Linux kernel for Amazon Web Services (AWS) systems
- linux-azure - Linux kernel for Microsoft Azure Cloud systems
- linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke - Linux kernel for Google Container Engine (GKE) systems
- linux-ibm - Linux kernel for IBM cloud systems

Details

Lonial Con discovered that the netfilter subsystem in the Linux kernel
contained a memory leak when handling certain element flush operations.
A local attacker could use this to expose sensitive information (kernel
memory). (CVE-2023-4569)

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)

It was discovered that a race condition existed in the AppleTalk
networking 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-2023-51781)

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)

Lonial Con discovered that the netfilter subsystem in the Linux kernel
did not properly handle element deactivation in certain cases, 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-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel
did not properly handle verdict parameters in certain cases, 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-2024-1086)

In the Linux kernel, the following vulnerability has been resolved: 
net: qualcomm: rmnet: fix global oob in rmnet_policy The variable
rmnet_link_ops assign a bigger maxtype which leads to a global out-of-
bounds read when parsing the netlink attributes. (CVE-2024-26597)
