See the Go 1.17.3 milestone on our issue tracker for details.

From the announcement e-mail:

[security] Go 1.17.3 and Go 1.16.10 are released

We have just released Go versions 1.17.3 and 1.16.10, minor point releases.
These minor releases include two security fixes following the security policy:

- archive/zip: don't panic on (*Reader).Open
  Reader.Open (the API implementing io/fs.FS introduced in Go 1.16) can be made
  to panic by an attacker providing either a crafted ZIP archive containing
  completely invalid names or an empty filename argument.
  Thank you to Colin Arnott, SiteHost and Noah Santschi-Cooney, Sourcegraph Code
  Intelligence Team for reporting this issue. This is CVE-2021-41772 and Go issue
  golang.org/issue/48085.
- debug/macho: invalid dynamic symbol table command can cause panic
  Malformed binaries parsed using Open or OpenFat can cause a panic when calling
  ImportedSymbols, due to an out-of-bounds slice operation.
  Thanks to Burak Çarıkçı - Yunus Yıldırım (CT-Zer0 Crypttech) for reporting this
  issue. This is CVE-2021-41771 and Go issue golang.org/issue/48990.
