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, and it is possible to violate Rust's alias rule and cause data race with Drain's Iterator implementation.

The flaw was corrected in 0.1.20 release of http crate.
