Duplicate Advisory

Original Description
Affected versions of this crate unconditionally implements Send for Bucket2. This allows sending non-Send types to other threads.
This can lead to data races when non Send types like Cell<T> or Rc<T> are contained inside Bucket2 and sent across thread boundaries. The data races can potentially lead to memory corruption (as demonstrated in the PoC from the original report issue).
The flaw was corrected in commit 15b2828 by adding a T: Send bound to the Send impl of Bucket2<T>.
The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
