Fixing snakeyaml vulnerability (CVE-2022-1471) on older ES versions

Elastic Stack Elasticsearch
1

I'm using ES version 5.6.X, and I would like to change snakeyaml package version to the one with the fix to CVE-2022-1471 - Meaning, I need to change the package version from 1.33 (I guess..) to 2.0 .

How can I do that?
Should it be in my DockerFile? Or in elasticsearch.yml file?

Elasticsearch 5 is very old and is no longer maintained.

We have never tested running Elasticsearch 5.6 with any version of SnakeYaml other than the one that it shipped with. It might work, but there are no guarantees.

If you care about resolving vulnerabilities then you need to migrate to a maintained version of Elasticsearch. No one is patching vulnerabilities in Elasticsearch 5 (or 6) anymore.

Elasticsearch 5.6 is EOL and no longer supported. Please upgrade ASAP.

Thanks @frens !
So it seems like this CVE still exists in latest ES version :frowning:

I've posted a new topic on that - mainly to understand the plan to fix it, and how I can change this package version manually.
