Similar minor problem here. An ancient version of GNU date was still in-use, and it didn't seem to like the year.

$ date -d "`date`" date: invalid date.

Indeed, date seems to be one of the things which required patching. On a retired, unpatched, SunOS 4.1.3_U1 machine, date returned strange things

So far most of the problem I've heard about involved people not installing patches for known issues before today. It would be interesting to see the traffic stats for Sun's, Oracle's, Microsoft's etc. download sites today as folks download the patches, which may have been available for a while, today.
