Description

A vulnerability has been discovered and corrected in systemtap :

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).

The updated packages have been patched to correct this issue.
