golang.org/x/crypto Vulnerable to Denial of Service (DoS) via Slow or Incomplete Key Exchange
SSH servers which implement file transfer protocols are vulnerable to a denial of service attack from clients which complete the key exchange slowly, or not at all, causing pending content to be read into memory, but never transmitted.

DoS in go-jose Parsing
### Impact
When parsing compact JWS or JWE input, go-jose could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of '.' characters.  An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service.

### Patches
Version 4.0.5 fixes this issue

### Workarounds
Applications could pre-validate payloads passed to go-jose do not contain an excessive number of '.' characters.
