SystemTap 1.4 and earlier, when unprivileged (aka stapusr) mode is
enabled, allows local users to cause a denial of service
(divide-by-zero error and OOPS) via a crafted ELF program with DWARF
expressions that are not properly handled by a stap script that
performs context variable access (CVE-2011-1769).

SystemTap 1.4, when unprivileged (aka stapusr) mode is enabled, allows
