Synopsis

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

Description

The version of libX11 installed on the remote host is prior to 1.6.0-2.2.16. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1859 advisory.

libX11: out-of-bounds memory access in _XkbReadKeySyms() (CVE-2023-43785)

libX11: integer overflow in XCreateImage() leading to a heap overflow. (CVE-2023-43787)

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 'yum update libX11' to update your system.
