Advisories for Cargo/Inventory package

Affected versions allow arbitrary caller-provided code to execute before the lifetime of main. If the caller-provided code accesses particular pieces of the standard library that require an initialized Rust runtime, such as std::io or std::thread, these may not behave as documented. Panics are likely; UB is possible. The flaw was corrected by enforcing that only code written within the inventory crate, which is guaranteed not to access runtime-dependent parts of …

Affected versions do not enforce a Sync bound on the type of caller-provided value held in the plugin registry. References to these values are made accessible to arbitrary threads other than the one that constructed them. A caller could use this flaw to submit thread-unsafe data into inventory, then access it as a reference simultaneously from multiple threads. The flaw was corrected by enforcing that data submitted by the caller …
