[Plugin: Add New Default Avatar [Emrikol's Fork]] Using TimThumb: security issue?

Hello,

I was reading this plugin’s description page and I noticed that it said that it used the TimThumb library to resize and cache thumbnails.
I remember a security scandal awhile back about TimThumb, and I was wondering if this plugin was safe to use.

Thanks, Shea.
