um, that's the wrong errata entry. For 3.4 -
006: SECURITY FIX: November 17, 2003
It may be possible for a local user to overrun the stack in
compat_ibcs2(8).
ProPolice catches this, turning a potential privilege escalation into
a denial of service. iBCS2 emulation does not need to be enabled via
sysctl(8) for this to happen.
A source code patch exists which remedies the problem.
