OT? Are chroots immune to buffer overflows?

[note: my question is WRT non-root chrooted jails - we all know about chroot'ing root processes!] Most buffer overflows I've seen attempt to infiltrate the system enough to run /bin/sh. In chroot'ed environments, /bin/sh doesn't (shouldn't!) exist - so they fail. Is it as simple as that? As 99.999% of the system binaries aren't available in the jail, can a buffer overflow ever work? -- Cheers Jason Haar Information Security Manager Trimble Navigation Ltd.
