Advisories for Golang/Gopkg.in/Yaml.v3 package

Due to unbounded alias chasing, a maliciously crafted YAML file can cause the system to consume significant system resources. If parsing user input, this may be used as a denial of service vector.

Parsing malicious or large YAML documents can consume excessive amounts of CPU or memory.

An issue in the Unmarshal function in Go-Yaml v3 causes the program to crash when attempting to deserialize invalid input.
