[USN-6609-3] Linux kernel (Oracle) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6609-3
February 06, 2024
linux-oracle, linux-oracle-5.15 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-oracle-5.15: Linux kernel for Oracle Cloud systems
Details:
Lin Ma discovered that the netfilter subsystem in the Linux kernel did not
properly validate network family support while creating a new netfilter
table. A local attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6040)
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly validate the server frame size in certain
situation, leading to an out-of-bounds read vulnerability. An attacker
could use this to construct a malicious CIFS image that, when operated on,
could cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2023-6606)
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)
Budimir Markovic, Lucas De Marchi, and Pengfei Xu discovered that the perf
subsystem in the Linux kernel did not properly validate all event sizes
when attaching new events, leading to an out-of-bounds write vulnerability.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2023-6931)
It was discovered that the IGMP protocol implementation in the Linux kernel
contained a race condition, 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-2023-6932)
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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:
linux-image-5.15.0-1050-oracle 5.15.0-1050.56
linux-image-oracle 5.15.0.1050.45
linux-image-oracle-lts-22.04 5.15.0.1050.45
Ubuntu 20.04 LTS:
linux-image-5.15.0-1050-oracle 5.15.0-1050.56~20.04.1
linux-image-oracle 5.15.0.1050.56~20.04.1
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.

[USN-6623-1] Django vulnerability
==========================================================================
Ubuntu Security Notice USN-6623-1
February 06, 2024
python-django vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
Summary:
Django could be made to denial of service if received a specially
crafted input.
Software Description:
- python-django: High-level Python web development framework
Details:
It was discovered that Django incorrectly handled certain inputs
that uses intcomma template filter. An attacker could possibly
use this issue to cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 23.10:
python3-django 3:4.2.4-1ubuntu2.1
Ubuntu 22.04 LTS:
python3-django 2:3.2.12-2ubuntu1.10
Ubuntu 20.04 LTS:
python3-django 2:2.2.12-1ubuntu0.21
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
python-django 1:1.11.11-1ubuntu1.21+esm3
python3-django 1:1.11.11-1ubuntu1.21+esm3
In general, a standard system update will make all the necessary changes.

Details:
USN-6610-1 fixed vulnerabilities in Firefox. The update introduced
several minor regressions. This update fixes the problem.
Original advisory details:
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2024-0741,
CVE-2024-0742, CVE-2024-0743, CVE-2024-0744, CVE-2024-0745, CVE-2024-0747,
