Name        : systemtap
Product     : Fedora 14
Version     : 1.4
Release     : 6.fc14
URL         : http://sourceware.org/systemtap/
Summary     : Instrumentation System
Description :
SystemTap is an instrumentation system for systems running Linux 2.6.
Developers can write instrumentation to collect data on the operation
of the system.

--------------------------------------------------------------------------------
Update Information:

Two divide-by-zero flaws were found in the way systemtap interpreted certain corrupted
DWARF expressions.  A privileged user able to execute arbitrary systemtap scripts could be
tricked into triggering this flaw to crash the target machine.  An unprivileged user (in the
stapusr group) may be able to trigger this flaw to crash the target machine, only if unprivileged
mode was enabled by the system administrator.
