With all due respect, this reads, smells and probably tastes like a backdoorIt's a bug. I recall it being found and fixed in AIX many years ago. Embarassing for Sun that it's still in Solaris, though. It's actually caused by a "feature" of login; the bug is in programs that exec login and pass "-froot" to it, and in preserving this feature of login at all. A quick Google search found Usenet postings about it from 1994; I'm sure it was known well before then.
Hi Michael. Thank you for making that issue public (about login). Haven't seen it posted anywhere. One note: although it could just as well be a bug, who says it was not a backdoor in the early 90's? Also, I understand this does not work on older Solaris/SunOS systems (anyone can verify?) which adds to my personal interest in the possibility. I refuse to believe someone is that funny/sad. Gadi.
