Those CVEs are related to gosu whose latest version is 1.14 which is the one bundled in the Bitnami container images. In the case of bitnami/nginx:

containers/bitnami/nginx/1.23/debian-11/Dockerfile

Line 38 in ef686fe

tar -zxf gosu-1.14.0-154-linux-amd64-debian-11.tar.gz -C /opt/bitnami --strip-components=2 --no-same-owner --wildcards '*/files' && \

You can also see that gosu is not affected by these issues, as it was confirmed by its maintainer.

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.
