Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-228 advisory.

In the Linux kernel, the following vulnerability has been resolved:

binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50240)

In the Linux kernel, the following vulnerability has been resolved:

binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50338)

A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue results from the improper handling of user-supplied data, which can lead to an assertion failure. This flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system.
(CVE-2023-2156)

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.

The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.

We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal kernel information. (CVE-2023-3567)

An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
This may result in denial of service or privilege escalation. (CVE-2023-35788)

In the Linux kernel, the following vulnerability has been resolved:

serial: 8250: Reinit port->pm on port specific driver unbind (CVE-2023-53176)

In the Linux kernel, the following vulnerability has been resolved:

mm: fix zswap writeback race condition (CVE-2023-53178)

In the Linux kernel, the following vulnerability has been resolved:

ACPICA: Avoid undefined behavior: applying zero offset to null pointer (CVE-2023-53182)

In the Linux kernel, the following vulnerability has been resolved:

irqchip/gicv3: Workaround for NVIDIA erratum T241-FABRIC-4 (CVE-2023-53383)

In the Linux kernel, the following vulnerability has been resolved:

rcu: Protect rcu_print_task_exp_stall() ->exp_tasks access (CVE-2023-53419)

In the Linux kernel, the following vulnerability has been resolved:

net: add vlan_get_protocol_and_depth() helper (CVE-2023-53433)

In the Linux kernel, the following vulnerability has been resolved:

net: skb_partial_csum_set() fix against transport header magic value (CVE-2023-53439)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update kernel --releasever 2023.1.20230628' or or 'dnf update --advisory ALAS2023-2023-228 --releasever 2023.1.20230628' to update your system.
