Are these bugs in execshield itself, or bugs in random applications,
or what?

Xpl017Elz's presentation focused on four (of a reported seven) attacks
he developed against Red Hat's Fedora Core using ExecShield. He
demonstrated privilege escalation, where a logged-in user can become
root and take over the machine, and remote code execution, wherein an
external attacker can gain root without a login.

What Xpl017Elz hadn't done yet, he explained later through a
translator, was notify Red Hat of his work. "This exploit code is not
very critical," he explained. "This is a proof of concept." Later he
conceded that it could be a significant vulnerability under some
circumstances, but remained ambivalent about contacting Red Hat.
