Details
As written in the advisory (Markdown source, shown as plain text).
ArcIntern::drop has a race condition where it can release memory which is about to get another user. The new user will get a reference to freed memory.
This was fixed by serializing access to an interned object while it is being deallocated.
Versions prior to 0.3.12 used stronger locking which avoided the problem.
