Helm is a program that allows users to creates packages which other users consume. Those packages contain files that are normally generated by Helm itself, but apparently if you alter your package definition by hand you can replace Chart.lock with a symlink.
As I'm typing this it's occurring to me that you probably shouldn't be able to do that. The fix they applied was to prevent the actual write from occurring when trying to write the lockfile and determining that the lockfile is a symlink. They could (should?) also validate that like, the package itself hasn't been screwed with in this manner.
