CVE-2020-36468

Name of the Vulnerable Software and Affected Versions cgc crate through 2020-12-10 for Rust

Description The issue concerns the cgc crate for Rust, where Ptr implements Send and Sync for all types, potentially leading to data races by sending non-thread safe types across threads. Additionally, 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, which can lead to data races when used across threads.

Recommendations As a temporary workaround, consider disabling the Ptr::write function until a patch is available. Restrict access to the Ptr module to minimize the risk of exploitation. Avoid using Ptr across threads until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
