NVD Description

Note: Versions mentioned in the description apply only to the upstream systemtap package and not the systemtap package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
