Applied 2 patches tonight to my old but still running
flawlessly and securely, OpenBSD 3.3 system. The patches
were 015_sysvshm.patch which has 2 links below, one
explaining the vulnerability & the other link to the
patch. I couldn't find any info on the 2nd patch,
016_ip6.patch, but I've had such good luck patching so
far, I went ahead & applied it too, & then rebuilt my
kernel & rebooted. So far, everything's jake.
