The crypto/tls package of Go through 1.16.5 does not properly assert that
the type of public key in an X.509 certificate matches the expected type
when doing a RSA based key exchange, allowing a malicious TLS server to
cause a TLS client to panic.

Notes

Author Note
mdeslaur Packages built using golang need to be rebuilt once the vulnerability has been fixed. This CVE entry does not list packages that need rebuilding outside of the main repository or the Ubuntu variants with PPA overlays.
