Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the HeaderProtectionKey::new_mask function. An attacker can induce a panic by sending a specially-crafted packet. This is only exploitable if overflow checking is enabled, which is not the default setting in release mode but can be enabled via RUSTFLAGS="-C overflow-checks" or overflow-checks = true in the Cargo.toml profile. Similarly, operations using AES_128_GCM and AES_256_GCM may also panic when processing large data chunks (about 64 gigabytes) under the same conditions, although common protocols like TLS and SSH are not affected as they process data in smaller segments.
