Ubuntu Security Notice USN-7599-1
June 25, 2025
python-urllib3 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.04
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
urllib3 could be made to expose sensitive information over the network.
Software Description:
- python-urllib3: HTTP library with thread-safe connection pooling
Details:
Jacob Sandum discovered that urllib3 handled redirects even when they were
explicitly disabled while using the PoolManager. An attacker could possibly
use this issue to obtain sensitive information. (CVE-2025-50181)
Illia Volochii discovered that urllib3 incorrectly handled retry and
redirect parameters when using Node.js. An attacker could possibly use this
issue to obtain sensitive information. This issue only affected Ubuntu
25.04. (CVE-2025-50182)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 25.04
python3-urllib3 2.3.0-2ubuntu0.1
Ubuntu 24.10
python3-urllib3 2.0.7-2ubuntu0.2
Ubuntu 24.04 LTS
python3-urllib3 2.0.7-1ubuntu0.2
Ubuntu 22.04 LTS
python3-urllib3 1.26.5-1~exp1ubuntu0.3

Ubuntu Security Notice USN-7595-3
June 25, 2025
linux-raspi-realtime vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-raspi-realtime: Linux kernel for Raspberry Pi Real-time systems
Details:
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly verify the target namespace when handling
upcalls. An attacker could use this to expose sensitive information.
(CVE-2025-2312)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS

Available with Ubuntu Pro
linux-image-raspi-realtime 6.8.0-2024.25
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.
