fix: gosec warnings

This commit fixes all gosec warnings either via ignoring the error, where it makes sense
or via fixing it. I have fixed multiple implicit memory aliasing errors in loops.
These can be dangerous. For more information: https://stackoverflow.com/questions/62446118/implicit-memory-aliasing-in-for-loop

Fixes: OSD-11463
