Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-082 advisory.

A flaw was found in the FreeRDP client when it fails to validate input data when using gateway connections. This flaw could allow a malicious gateway to send a specially crafted input to a client leading to an out of bounds write in client memory. The highest threat from this flaw is that it could allow arbitrary code to be executed on the target system. (CVE-2021-41159)
