Mandriva Linux Security Advisory MDVSA-2011:155
http://www.mandriva.com/security/

Package : systemtap
Date : October 17, 2011
Affected: 2011.

Problem Description:

Multiple vulnerabilities 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).

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) (CVE-2011-1781).

The updated packages have been patched to correct these issues.
