go -- multiple vulnerabilities

The Go project reports:

encoding/pem: fix stack overflow in Decode.
A large (more than 5 MB) PEM input can cause a stack
overflow in Decode, leading the program to crash.

crypto/elliptic: tolerate all oversized scalars in generic
P-256.
A crafted scalar input longer than 32 bytes can
cause P256().ScalarMult or P256().ScalarBaseMult to panic.
Indirect uses through crypto/ecdsa and crypto/tls are
unaffected. amd64, arm64, ppc64le, and s390x are
unaffected.

crypto/x509: non-compliant certificates can cause a panic
in Verify on macOS in Go 1.18.
Verifying certificate chains containing certificates
which are not compliant with RFC 5280 causes
Certificate.Verify to panic on macOS. These chains can be
delivered through TLS and can cause a crypto/tls or
net/http client to crash.
