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)
