Related to Apache and hacking - ExtremeTech issued an update to an Apache
security problem they reported on June 17th.  Apparently the problem is more
serious than first reported.  On Intel based machines running various
flavors of Unix (including Linux) a hacker may be able to gain root access.
The report also says that the problem is even more serious (if it could be)
on MS systems running Apache.  They recommend patching immediately and gave
the following URLs for further information:

hole allows root access", at www.extremetech.com.
