What is this beige goo in my freezer?

[Parsnip3932]

 

Hello,

I recently got a second hand freezer, and it has this beige goo in it (see picture).

What is the goo? Something to do with insulation? It seems to have decomposed a bit! It's sticky to the touch and there's a gap in the exit hole.

How can I fix it and how can I prevent it from happening again?

Thanks in advance for your help,
