Bump Gosu

[coltonfreeman26]

Name and Version

bitnami/tomcat:10.1.1

What is the problem this feature will solve?

Remove high and critical vulnerabilities found in /opt/bitnami/common/bin/gosu compiled with go-1.16.7

What is the feature you are proposing to solve the problem?

Update gosu to bump the go version to resolve these findings.

What alternatives have you considered?

Sorry for the issue template. I know this is not what this typically is for.
We are using the bitnami/tomcat:10.1.1 image and our scan tools are picking up a bunch of high and crit findings in regards to go from /opt/bitnami/common/bin/gosu. Is it possible to bump yalls version of gosu to help with these findings?
Please let me know if you need me to provide any more information or details.

@coltonfreeman26 Please, read this conversation #7419, and particularly, this comment #7419 (comment).

A HIGH or CRITICAL vulnerability does not mean ALWAYS a risk.

Hello @recena thank you for that info, it is very helpful.

You can close this issue but also just found out Gosu is not needed unless running container as root which we are not.

Again thank you for the help.

Hi, we are glad to announce that we got rid of gosu in all Bitnami container images, so the false positives previously reported by some CVE scanners will not appear anymore:

From now on, gosu functionalities were replaced by chroot. In this PR you can find an example of this implementation.
