Fixes the following security issues (1.33.2):
- CVE-2019-17596: Invalid DSA public keys can cause a panic in dsa.Verify.
In particular, using crypto/x509.Verify on a crafted X.509 certificate
chain can lead to a panic, even if the certificates don’t chain to a
trusted root. The chain can be delivered via a crypto/tls connection to a
client, or to a server that accepts and verifies client certificates.
net/http clients can be made to crash by an HTTPS server, while net/http
servers that accept client certificates will recover the panic and are
unaffected.
Additionally, 1.13.3 fixes a number of issues. From the release notes:
Fixes to the go command, the toolchain, the runtime, syscall, net, net/http,
and crypto/ecdsa packages
