Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The dcrypt-api crate, versions before 2.0.0, has safe ErrorRegistry operations that can cause undefined behavior when the default std feature is enabled. Ordinary safe Rust code calling the registry can trigger mismatched deallocation, type confusion, and use-after-free, and crates that re-export this API are affected too. Upgrade to dcrypt-api 2.0.0 or later; the source says there is no reliable workaround while using the affected registry API.
