I'm working on a quick little programming project for a client and ran across this in the man page for access(2) "Access() is a potential security hole and should never be used." Obviously, I could use stat() instead, but use of access() will make this project so simple it's not even funny. Since that message is rather brief, I went looking for some more information. In the source tree I found a number of programs that use access() - including tcsh, sendmail and perl. I'm a little confused here, if access() is such a serious security problem that it should _never_ be used, do we now have a major problem with a large amount of software in the base system? Does anyone have a pointer to more detailed information on the potential security hole in access()? I've got a bit more research to do on this, but I'd appreciate any pointers to speed me along. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
