How to fix?

Upgrade Amazon-Linux:2 libcurl-devel to version 0:7.79.1-6.amzn2.0.1 or higher.
This issue was patched in ALAS2-2022-1875.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl-devel package and not the libcurl-devel package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.
