+ <h5>Issue 1:</h5>
+ <p>
+ Users are always granted permissions to cd into a directory. The
+ check for whether execute is present on directories is a de-facto
+ no-op. This cannot be mitigated without upgrading. Even setting
+ an explicit "deny - execute" NFSv4 ACE will be bypassed.
+ </p>
+ <h5>Issue 2:</h5>
+ <p>
+ All ACEs for the owner_group (group@) and regular groups
+ (group:<foo>) are granted the current user. This means that
+ POSIX mode 770 is de-facto 777, and the below ACL is also de-facto
+ 777 because the groupmember check for builtin_administrators
+ returns True.
