One quick way to figure out whether your systems is affected is to run the command `uname -a` on your machine. The output should tell you which branch you are following as well as the date that it was built. You should make sure that you have both CVSup'd your sources AND rebuilt the system since the correction date stated for you branch. Compare the date/branch from your machine to those from the advisory. For example, my `uname -a` output is something like: FreeBSD [removed] 4.6-STABLE FreeBSD 4.6-STABLE #0: Tue Jul 30 18:31:32 PDT 2002 [removed]:/usr/obj/usr/src/sys/SMP i386 I am running 4.6-STABLE, which means that I am following the RELENG_4 branch. I can also see that I rebuilt my system at 18:31:32 on July 30th of this year. Because my time is kept as Pacific Daylight Time(PDT), I have to correct to Universal Coordinated Time(UTC). So, my system looks like this relative to the correction date: My system: 2002-07-30 11:31:32 UTC (RELENG_4) Fix date: 2002-06-23 22:34:52 UTC (RELENG_4) I'm safe on this particular problem, as it was fixed on June 23, but I CVSup my sources every week and I rebuilt my system on July 30th.
