python2.7 regresssions
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
USN-7015-5 caused some regressions in Python.
Software Description:
- python2.7: An interactive high-level object-oriented language
Details:
USN-7015-5 fixed vulnerabilities in python2.7. The update introduced
several minor regressions. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that the Python email module incorrectly parsed email
addresses that contain special characters. A remote attacker could
possibly use this issue to bypass certain protection mechanisms.
(CVE-2023-27043)
It was discovered that Python allowed excessive backtracking while parsing
certain tarfile headers. A remote attacker could possibly use this issue
to cause Python to consume resources, leading to a denial of service.
(CVE-2024-6232)
It was discovered that the Python email module incorrectly quoted newlines
for email headers. A remote attacker could possibly use this issue to
perform header injection. (CVE-2024-6923)
It was discovered that the Python http.cookies module incorrectly handled
parsing cookies that contained backslashes for quoted characters. A remote
attacker could possibly use this issue to cause Python to consume
resources, leading to a denial of service. (CVE-2024-7592)
It was discovered that the Python zipfile module incorrectly handled
certain malformed zip files. A remote attacker could possibly use this
issue to cause Python to stop responding, resulting in a denial of
service. (CVE-2024-8088)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
python2.7 2.7.18-13ubuntu1.4

[USN-7120-3] Linux kernel (Low Latency) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-7120-3
November 21, 2024
linux-lowlatency, linux-lowlatency-hwe-6.8 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-lowlatency: Linux low latency kernel
- linux-lowlatency-hwe-6.8: Linux low latency kernel
Details:
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- File systems infrastructure;
- Network traffic control;
(CVE-2024-46800, CVE-2024-43882)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.8.0-49-lowlatency 6.8.0-49.49.1
linux-image-6.8.0-49-lowlatency-64k 6.8.0-49.49.1
linux-image-lowlatency 6.8.0-49.49.1
linux-image-lowlatency-64k 6.8.0-49.49.1
linux-image-lowlatency-64k-hwe-24.04 6.8.0-49.49.1
linux-image-lowlatency-hwe-24.04 6.8.0-49.49.1
Ubuntu 22.04 LTS
linux-image-6.8.0-49-lowlatency 6.8.0-49.49.1~22.04.1
linux-image-6.8.0-49-lowlatency-64k 6.8.0-49.49.1~22.04.1
linux-image-lowlatency-64k-hwe-22.04 6.8.0-49.49.1~22.04.1
linux-image-lowlatency-hwe-22.04 6.8.0-49.49.1~22.04.1
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.
