CVE-2011-1781 not yet assigned priority: Debian including 1 source packages (systemtap), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
SystemTap 1.4, 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 stack unwinding (aka backtracing).
