[USN-6726-3] Linux kernel (Xilinx ZynqMP) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6726-3
April 17, 2024
linux-xilinx-zynqmp vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors
Details:
Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)
It was discovered that the IPv6 implementation of the Linux kernel did not
properly manage route cache memory usage. A remote attacker could use this
to cause a denial of service (memory exhaustion). (CVE-2023-52340)
It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-52429, CVE-2024-23851)
Dan Carpenter discovered that the netfilter subsystem in the Linux kernel
did not store data in properly sized memory locations. A local user could
use this to cause a denial of service (system crash). (CVE-2024-0607)
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:
- Architecture specifics;
- Cryptographic API;
- Android drivers;
- EDAC drivers;
- GPU drivers;
- Media drivers;
- MTD block device drivers;
- Network drivers;
- NVME drivers;
- TTY drivers;
- Userspace I/O drivers;
- F2FS file system;
- GFS2 file system;
- IPv6 Networking;
- AppArmor security module;

CVE-2023-52439, CVE-2023-52612, CVE-2024-26633, CVE-2024-26597,
CVE-2023-52449, CVE-2023-52444, CVE-2023-52609, CVE-2023-52469,
CVE-2023-52445, CVE-2023-52451, CVE-2023-52470, CVE-2023-52454,
CVE-2023-52436, CVE-2023-52438)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS:
linux-image-5.4.0-1041-xilinx-zynqmp 5.4.0-1041.45
linux-image-xilinx-zynqmp 5.4.0.1041.41
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-6729-2] Apache HTTP Server vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6729-2
April 17, 2024
apache2 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
Summary:
Several security issues were fixed in Apache HTTP Server.
Software Description:
- apache2: Apache HTTP server
Details:
USN-6729-1 fixed several vulnerabilities in Apache. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
Original advisory details:
Orange Tsai discovered that the Apache HTTP Server incorrectly handled
validating certain input. A remote attacker could possibly use this
issue to perform HTTP request splitting attacks. (CVE-2023-38709)
Keran Mu and Jianjun Chen discovered that the Apache HTTP Server
incorrectly handled validating certain input. A remote attacker could
possibly use this issue to perform HTTP request splitting attacks.
(CVE-2024-24795)
Bartek Nowotarski discovered that the Apache HTTP Server HTTP/2 module
incorrectly handled endless continuation frames. A remote attacker could
possibly use this issue to cause the server to consume resources, leading
to a denial of service. This issue was addressed only in Ubuntu 18.04 LTS.
(CVE-2024-27316)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
apache2 2.4.29-1ubuntu4.27+esm2
Ubuntu 16.04 LTS (Available with Ubuntu Pro):
apache2 2.4.18-2ubuntu3.17+esm12
