I am doing some practice on environment variable overflow on sparc/solaris. But the environment variable are string based, in other word, I can't have \x00 byte inside the variable, and as a result, I can't put the heap address inside cuz this won't be parsed in correctly. Anybody can tell me wether there is anyway aroud this? Also, For SIGURG from OOB signal(in SPARC/solaris) , will its signal handler block another SIGURG from re-entering untill the first one got handled?
