Ubuntu Security Notice USN-5358-1

Ubuntu Security Notice USN-5358-1
Posted Mar 31, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5358-1 - It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.13, linux-hwe-5.4,
linux-kvm, linux-oracle, linux-oracle-5.4 vulnerabilities
==========================================================================

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

- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 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-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-hwe-5.13: Linux hardware enablement (HWE) kernel
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the network traffic control implementation in the
Linux kernel contained 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-2022-1055)

It was discovered that the IPsec implementation in the Linux
kernel did not properly allocate enough memory when performing ESP
transformations, leading to a heap-based buffer overflow. A local
attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-27666)

Update instructions:

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

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.
