Source Advisory Statement

### Summary `loona-hpack` suffers from the same vulnerability as the original `hpack` as documented in https://github.com/mlalic/hpack-rs/issues/11 ### Details The original includes a very nice description of the problem, as well as an easy-enough fix for it. ### PoC The original example pretty much still applies: ```rust use loona_hpack::Decoder; pub fn main() { let input = &[0x3f]; let mut decoder = Decoder::new(); let _ = decoder.decode(input); } ``` ### Impact From the original: `All users who try to decode untrusted input using the Decoder are vulnerable to this exploit. A patched version of the crate is available on [crates.io](https://crates.io/crates/hpack-patched) under the name hpack-patched. See [Cargo's documentation on overriding dependencies](https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html) for more information.`
