Gradle is a build tool with a focus on build automation and support for
multi-language development. When copying or archiving symlinked files,
Gradle resolves them but applies the permissions of the symlink itself
instead of the permissions of the linked file to the resulting file. This
leads to files having too much permissions given that symlinks usually are
world readable and writeable. While it is unlikely this results in a direct
vulnerability for the impacted build, it may open up attack vectors
depending on where build artifacts end up being copied to or un-archived.
In versions 7.6.3, 8.4 and above, Gradle will now properly use the
permissions of the file pointed at by the symlink to set permissions of the
copied or archived file.
