Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.4.276-189.376. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2024-069 advisory.

2024-07-03: CVE-2024-36904 was added to this advisory.

2024-07-03: CVE-2024-36954 was added to this advisory.

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

netfilter: nftables: exthdr: fix 4-byte stack OOB write

If priv->len is a multiple of 4, then dst[len / 4] can write pastthe destination array which leads to stack corruption.

This construct is necessary to clean the remainder of the registerin case ->len is NOT a multiple of the register size, so make itconditional just like nft_payload.c does.

The bug was added in 4.1 cycle and then copied/inherited whentcp/sctp and ip option support was added.
