For those using FreeBSD, there has been another security update to the 7.1 release family.  According to the UPDATING file:

20090323:       p4      FreeBSD-SA-09:06.ktimer, FreeBSD-EN-09:01.kenv<br /> Correctly sanity-check timer IDs. [SA-09:06]<br /> Limit the size of malloced buffer when dumping environment<br /> variables. [EN-09:01]

If you’re interested in applying this update to your system, here is the method I use:

csup -g -L2 cvsup.freebsd.org /usr/share/examples/cvsup/standard-supfile<br /> cd /usr/src<br /> make buildkernel && make installkernel<br /> make buildworld && make installworld<br /> reboot

There are other methods for keeping your base system updated, but I prefer the compiling method. What other methods might you suggest?
