Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.4.0-1127-fips 5.4.0-1127.137
Available with Ubuntu Pro

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.

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.

[USN-7926-1] OpenStack Keystone vulnerabilities
==========================================================================
Ubuntu Security Notice USN-7926-1
December 11, 2025
keystone vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in OpenStack Keystone.
Software Description:
- keystone: OpenStack identity service
Details:
Kay discovered that OpenStack Keystone incorrectly handled the ec2tokens
and s3tokens APIs. A remote attacker could possibly use this issue to
obtain unauthorized access and escalate privileges. (CVE-2025-65073)
It was discovered that OpenStack Keystone only validated the first 72
bytes of an application secret. An attacker could possibly use this issue
to bypass password complexity. (CVE-2021-3563)
It was discovered that OpenStack Keystone had a time lag before a token
should be revoked by the security policy. A remote administrator could use
this issue to maintain access for longer than expected. (CVE-2022-2447)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
keystone 2:21.0.1-0ubuntu2.1
python3-keystone 2:21.0.1-0ubuntu2.1
In general, a standard system update will make all the necessary changes.

- Ubuntu 25.10
- Ubuntu 25.04
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in urllib3.
Software Description:
- python-urllib3: HTTP library with thread-safe connection pooling
Details:
Illia Volochii discovered that urllib3 did not limit the steps in a
decompression chain. An attacker could possibly use this issue to cause
urllib3 to use excessive resources, causing a denial of service.
(CVE-2025-66418)
Rui Xi discovered that urllib3 incorrectly handled highly compressed data.
An attacker could possibly use this issue to cause urllib3 to use excessive
resources, causing a denial of service. This issue only affected Ubuntu
24.04 LTS, Ubuntu 25.04, and Ubuntu 25.10. (CVE-2025-66471)
For the brotli encoding, the fix for CVE-2025-66471 requires an additional
security update in the brotli package.
