Description

curl's code for managing SSH connections when SFTP was done using the wolfSSH
powered backend was flawed and missed host verification mechanisms.

This prevents curl from detecting MITM attackers and more.

Remediation Steps

• Update the affected package curl-minimal from version 8.11.1-4.amzn2023.0.1 to 8.15.0-4.amzn2023.0.1.
