Withdrawn Advisory: Infinite loop in xz
### Withdrawn Advisory
This advisory has been withdrawn because alerts cannot be issued for the Go standard library at this time.

### Original Description
Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.

golang.org/x/net/http vulnerable to ping floods
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

golang.org/x/net/http vulnerable to a reset flood
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. Servers that accept direct connections from untrusted clients could be remotely made to allocate an unlimited amount of memory, until the program crashes. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
