[USN-6864-3] Linux kernel (GKE) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6864-3
July 11, 2024
linux-gke 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-gke: Linux kernel for Google Container Engine (GKE) systems
Details:
It was discovered that the Intel Data Streaming and Intel Analytics
Accelerator drivers in the Linux kernel allowed direct access to the
devices for unprivileged users and virtual machines. A local attacker could
use this to cause a denial of service. (CVE-2024-21823)
A security issue was discovered in the Linux kernel.
An attacker could possibly use it to compromise the system.
This update corrects flaws in the following subsystem:
- Netfilter;
(CVE-2024-26924)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.8.0-1005-gke 6.8.0-1005.8
linux-image-gke 6.8.0-1005.8
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-6894-1] Apport vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6894-1
July 11, 2024
apport vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in Apport.
Software Description:
- apport: automatically generate crash reports for debugging
Details:
Muqing Liu and neoni discovered that Apport incorrectly handled detecting
if an executable was replaced after a crash. A local attacker could
possibly use this issue to execute arbitrary code as the root user.
(CVE-2021-3899)
Gerrit Venema discovered that Apport incorrectly handled connections to
Apport sockets inside containers. A local attacker could possibly use this
issue to connect to arbitrary sockets as the root user. (CVE-2022-1242)
Gerrit Venema discovered that Apport incorrectly handled user settings
files. A local attacker could possibly use this issue to cause Apport to
consume resources, leading to a denial of service. (CVE-2022-28652)
Gerrit Venema discovered that Apport did not limit the amount of logging
from D-Bus connections. A local attacker could possibly use this issue to
fill up the Apport log file, leading to a denial of service.
(CVE-2022-28654)
Gerrit Venema discovered that Apport did not filter D-Bus connection
strings. A local attacker could possibly use this issue to cause Apport to
make arbitrary network connections. (CVE-2022-28655)
Gerrit Venema discovered that Apport did not limit the amount of memory
being consumed during D-Bus connections. A local attacker could possibly
use this issue to cause Apport to consume memory, leading to a denial of
service. (CVE-2022-28656)
Gerrit Venema discovered that Apport did not disable the python crash
handler before chrooting into a container. A local attacker could possibly
use this issue to execute arbitrary code. (CVE-2022-28657)
Gerrit Venema discovered that Apport incorrectly handled filename argument
whitespace. A local attacker could possibly use this issue to spoof
arguments to the Apport daemon. (CVE-2022-28658)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS
apport 2.20.1-0ubuntu2.30+esm4
Available with Ubuntu Pro
python-apport 2.20.1-0ubuntu2.30+esm4
Available with Ubuntu Pro
python3-apport 2.20.1-0ubuntu2.30+esm4
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.

[USN-6885-2] Apache HTTP Server regression
==========================================================================
Ubuntu Security Notice USN-6885-2

apache2 regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
USN-6885-1 introduced a regression in Apache HTTP Server.
Software Description:
- apache2: Apache HTTP server
Details:
USN-6885-1 fixed vulnerabilities in Apache HTTP Server. One of the security
fixes introduced a regression when proxying requests to a HTTP/2 server.
This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Marc Stern discovered that the Apache HTTP Server incorrectly handled
serving WebSocket protocol upgrades over HTTP/2 connections. A remote
attacker could possibly use this issue to cause the server to crash,
resulting in a denial of service. (CVE-2024-36387)
Orange Tsai discovered that the Apache HTTP Server mod_proxy module
incorrectly sent certain request URLs with incorrect encodings to backends.
A remote attacker could possibly use this issue to bypass authentication.
(CVE-2024-38473)
Orange Tsai discovered that the Apache HTTP Server mod_rewrite module
incorrectly handled certain substitutions. A remote attacker could possibly
use this issue to execute scripts in directories not directly reachable
by any URL, or cause a denial of service. Some environments may require
using the new UnsafeAllow3F flag to handle unsafe substitutions.
(CVE-2024-38474, CVE-2024-38475, CVE-2024-39573)
Orange Tsai discovered that the Apache HTTP Server incorrectly handled
certain response headers. A remote attacker could possibly use this issue
to obtain sensitive information, execute local scripts, or perform SSRF
attacks. (CVE-2024-38476)
Orange Tsai discovered that the Apache HTTP Server mod_proxy module
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause the server to crash, resulting in a denial of service.
(CVE-2024-38477)
It was discovered that the Apache HTTP Server incorrectly handled certain
handlers configured via AddType. A remote attacker could possibly use this
issue to obtain source code. (CVE-2024-39884)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
apache2 2.4.58-1ubuntu8.3
Ubuntu 22.04 LTS
apache2 2.4.52-1ubuntu4.11
Ubuntu 20.04 LTS
