TimThumb Brouhaha

[DoktorThomas]

I just read "the TimThumb Saga" on MA.tt. I am not a professional coder but know my way around css, html and php to find most problems (broken/missing code). The ranting on TimThumb has me confused mostly because of the statement that the hackable code from TimThumb is inculcated into many paid-for themes not in the WP repository. Obviously, the StudioPress themes are not in the repository, so that begs the question, "Should us Gensis users be concerned about TimThimb code?"
[No, I have not added a plugin to any theme in use that mentions TimThumb. I generally size/re-size my media externally on my PC and up load it as "full size".]
