USN-6700-2: Linux kernel (AWS) vulnerabilities

Read Time:1 Minute, 44 Second

It was discovered that the Layer 2 Tunneling Protocol (L2TP) implementation
in the Linux kernel contained a race condition when releasing PPPoL2TP
sockets in certain conditions, 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-2022-20567)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle block device modification while it is
mounted. A privileged attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-34256)

Eric Dumazet discovered that the netfilter subsystem in the Linux kernel
did not properly handle DCCP conntrack buffers in certain situations,
leading to an out-of-bounds read vulnerability. An attacker could possibly
use this to expose sensitive information (kernel memory). (CVE-2023-39197)

It was discovered that a race condition existed in the AppleTalk networking
subsystem of the Linux kernel, 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-2023-51781)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle the remount operation in certain cases,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2024-0775)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, 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-2024-1086)

It was discovered that a race condition existed in the SCSI Emulex
LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF
and re-scanning an HBA FCF table, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-24855)

USN-6709-1: OpenSSL vulnerabilities

Read Time:49 Second

It was discovered that checking excessively long DH keys or parameters
may be very slow. A remote attacker could possibly use this issue to
cause OpenSSL to consume resources, resulting in a denial of service.
(CVE-2023-3446)

After the fix for CVE-2023-3446 Bernd Edlinger discovered that a large
q parameter value can also trigger an overly long computation during
some of these checks. A remote attacker could possibly use this issue
to cause OpenSSL to consume resources, resulting in a denial of
service. (CVE-2023-3817)

David Benjamin discovered that generating excessively long X9.42 DH
keys or checking excessively long X9.42 DH keys or parameters may be
very slow. A remote attacker could possibly use this issue to cause
OpenSSL to consume resources, resulting in a denial of service.
(CVE-2023-5678)

Bahaa Naamneh discovered that processing a maliciously formatted
PKCS12 file may lead OpenSSL to crash leading to a potential Denial of
Service attack. (CVE-2024-0727)

USN-6707-2: Linux kernel (ARM laptop) vulnerabilities

Read Time:40 Second

Lonial Con discovered that the netfilter subsystem in the Linux kernel did
not properly handle element deactivation in certain cases, 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-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, 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-2024-1086)

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:
– Network drivers;
– PWM drivers;
(CVE-2024-26597, CVE-2024-26599)

USN-6704-2: Linux kernel (Raspberry Pi) vulnerabilities

Read Time:1 Minute, 9 Second

It was discovered that the NVIDIA Tegra XUSB pad controller driver in the
Linux kernel did not properly handle return values in certain error
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-23000)

Quentin Minster discovered that the KSMBD implementation in the Linux
kernel did not properly handle session setup requests. A remote attacker
could possibly use this to cause a denial of service (memory exhaustion).
(CVE-2023-32247)

Lonial Con discovered that the netfilter subsystem in the Linux kernel did
not properly handle element deactivation in certain cases, 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-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
