Andrew Walker reports:

+
Issue 1:
+
+ 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. +
+
Issue 2:
+
+ 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. +
