[Security] Bump h2 from 0.3.16 to 0.3.18

Ghost User requested to merge dependabot-cargo-h2-0.3.18 into master

Bumps h2 from 0.3.16 to 0.3.18. This update includes a security fix.

Vulnerabilities fixed

h2 vulnerable to denial of service Hyper is an HTTP library for Rust and h2 is an HTTP 2.0 client & server implementation for Rust. An issue was discovered in h2 v0.2.4 when processing header frames. Both packages incorrectly process the HTTP2 RST_STREAM frames by not always releasing the memory immediately upon receiving the reset frame, leading to stream stacking. As a result, the memory and CPU usage are high which can lead to a Denial of Service (DoS).

As of time of publication of this advisory, there is no evidence of a fix having been incorporated into h2.

This issue affects users only when dealing with http2 connections.

Patched versions: 0.3.17 Affected versions: <= 0.3.16; < 0.3.17
