From the mailing list announcement:

[security] Go 1.20.7 and Go 1.19.12 are released

Hello gophers,

We have just released Go versions 1.20.7 and 1.19.12, minor point releases.

These minor releases include 1 security fixes following the security policy:

- crypto/tls: restrict RSA keys in certificates to <= 8192 bits

  Extremely large RSA keys in certificate chains can cause a client/server
  to expend significant CPU time verifying signatures. Limit this by
  restricting the size of RSA keys transmitted during handshakes to <=
  8192 bits.

  Based on a survey of publicly trusted RSA keys, there are currently only
  three certificates in circulation with keys larger than this, and all
  three appear to be test certificates that are not actively deployed. It
  is possible there are larger keys in use in private PKIs, but we target
  the web PKI, so causing breakage here in the interests of increasing the
  default safety of users of crypto/tls seems reasonable.

  Thanks to Mateusz Poliwczak for reporting this issue.
