CVE-2020-36467 | playxe/cgc Security vulnerabilities

Description

Affected versions of this crate have the following issues:

Ptr implements Send and Sync for all types, this can lead to data races by sending non-thread safe types across threads.
Ptr::get violates mutable alias rules by returning multiple mutable references to the same object.
Ptr::write uses non-atomic writes to the underlying pointer. This means that when used across threads it can lead to data races.
