Erik Sjoelund discovered that a race condition in the stap tool shipped
by Systemtap, an instrumentation system for Linux 2.6, allows local
privilege escalation for members of the stapusr group.
The old stable distribution (etch) isnβt affected.
For the stable distribution (lenny), this problem has been fixed in
version 0.0.20080705-1+lenny1.
For the unstable distribution (sid), this problem has been fixed in
version 0.0.20090314-2.
We recommend that you upgrade your systemtap package.
