well, if one makes workaround that is not checking versions, then one is in trouble anyway and should have reported that bug in the first place; normally bugs in pdftex are solved pretty fast so writing a workaround may have taken more time. 

also, i assume that security issues (as well as fixes and side effects)  are investigated first; it may be that pdftex is never affected by the issue at all, in which case no update is needed (btw, for me 'security fix' is just a nice word for a 'programming error' or 'severe bug' which may happen to have a security side effect; to some extend i guess that users can mess up their live more with using tex the wrong way than with some occasional crash, which if i remember right has not happend that often, esp not in library parts but i may be wrong)
