INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Ubuntu 20.04
Focal install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y

* CVE-2024-36288: Memory corruption in SUNRPC_GSS.

A missing check when using SUNRPC_GSS could lead to an out-of-bounds
memory access. A local attacker could use this flaw to cause memory
corruption.


* CVE-2024-36883: Denial-of-service in Networking namespace driver.

A race condition when using the Networking namespace driver could lead to
an out-of-bounds memory access. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-36886: Remote code execution in TIPC networking stack.

A logic error when using the TIPC networking stack could lead to a
use-after-free. A remote attacker could use this flaw to execute
arbitrary code in kernel mode, escalate privileges, cause a
denial-of-service, or aid in other types of attacks.


* CVE-2024-36904: Remote code execution in TCP/IP networking stack.

A race condition in TCP/IP networking stack can cause a data race
with a refcount value, leading to an underflow, which can cause a
use-after-free elsewhere in the kernel depending on the refcount.
A remote attacker could use this flaw to execute arbitrary code in
kernel mode, escalate privileges, cause a denial-of-service, or aid
in other types of attacks.


* CVE-2024-36919: Denial-of-service in QLogic Fibre-Channel-over-Ethernet offload driver.

Unnecessary locking when using the QLogic FCoE offload driver could
lead to a kernel panic. A local attacker could use this flaw to cause
a denial-of-service.


* CVE-2024-36933: Information leak in Network Service Header protocol stack.

A logic error when using the Network Service Header protocol stack could
lead to an out-of-bounds memory access. A local attacker could use this
flaw to extract sensitive information.

A logic error when using Open vSwitch driver could lead to destination
address being partially zeroed out. A local attacker could use this flaw
to cause a denial-of-service.


* CVE-2024-38578: Information leak in Linux filesystem encryption layer.

A logic error when using Linux filesystem encryption layer could lead to
an out-of-bounds memory write. A local attacker could use this flaw to
extract sensitive information.


* CVE-2024-38598: Denial-of-service in multiple block device driver.

A logic error when using multiple block device driver could lead to
soft-lockup. A local attacker could use this flaw to cause a denial-of-
service.


* CVE-2024-38599: Disk corruption in JFFS2 filesystem.

A missing check when using JFFS2 filesystem could lead to an out-of-
bounds memory write. A local attacker could use this flaw to cause disk
corruption.


* CVE-2024-38618: Denial-of-service in the core sound subsystem (ALSA).

A missing check in the timer code of the core sound subsystem (ALSA)
could lead to tasks being stalled. A local attacker could use this
flaw to cause a denial-of-service.


* CVE-2024-38659: Information leak in Cisco VIC Ethernet driver.

A missing check when using Cisco VIC Ethernet driver could lead to an
out-of-bounds memory read. A local attacker could use this flaw to
extract sensitive information.


* CVE-2024-39276: Resource leak in ext4 filesystem.

Incorrect reference counting when using ext4 filesystem could lead to a
reference count leak. A local attacker could use this flaw to cause a
denial-of-service.
