[rsyslog] security issue in rsyslog

[Rainer Gerhards]

... and the patch will not work on all of these version, due to the
introduction of the netstream driver functionality. Please note that
anything older than current v3-stable is outdated, so the proper way to
replace the faulty code is to upgrade to the current v3-stable and apply
the patch. I will also release a new v3-stable soon, hopefully today
(but I'd like to conduct some more tests).
