+description = """
+Affected versions of this crate incorrectly used raw pointer,
+which introduced unsoundness in its public safe API.
+
+[Failing to drop the Drain struct causes double-free](https://github.com/hyperium/http/issues/354),
+and [it is possible to violate Rust's alias rule and cause data race with Drain's Iterator implementation](https://github.com/hyperium/http/issues/355).
+
+The flaw was corrected in 0.2.0 release of `http` crate.
