[Security] Bump http from 0.1.21 to 0.2.1

[dependabot-preview]

Bumps http from 0.1.21 to 0.2.1. This update includes security fixes.

Vulnerabilities fixed

Sourced from The RustSec Advisory Database.

HeaderMap::Drain API is unsound 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 0.2.0 release of http crate.

Patched versions: >= 0.2.0 Unaffected versions: none

Sourced from The RustSec Advisory Database.

Integer Overflow in HeaderMap::reserve() can cause Denial of Service HeaderMap::reserve() used usize::next_power_of_two() to calculate the increased capacity. However, next_power_of_two() silently overflows to 0 if given a sufficently large number in release mode.

If the map was not empty when the overflow happens, the library will invoke self.grow(0) and start infinite probing. This allows an attacker who controls the argument to reserve() to cause a potential denial of service (DoS).

The flaw was corrected in 0.2.0 release of http crate.
