Details

As written in the advisory (Markdown source, shown as plain text).

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. ### Specific Go Packages Affected golang.org/x/net/http2
