CVE-2020-36449

Name of the Vulnerable Software and Affected Versions kekbit crate versions prior to 0.3.4

Description The issue allows users to send H: !Send to other threads, which can potentially lead to data races and undefined behavior. This is because Send is implemented for ShmWriter<H> without requiring H: Send.

Recommendations For versions prior to 0.3.4, update to version 0.3.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of ShmWriter<H> to prevent sending H: !Send to other threads until a patch is available.
