[dns-operations] difference between dns spoofing and dns hijacking?

[Lauren C.]

I saw the info from google,

While the DNS hijacking involves a malware, the DNS Cache poisoning 
involves overwriting your local DNS cache with fake values that redirect 
your browser to malicious websites. ... Though DNS Cache Poisoning and 
DNS Hijacking are used interchangeably, there is a small difference 
between them.

Not very sure about the explanation.
Can you kindly expand it?

thanks.
