No. FreeBSD's "Linux mode" is nothing more or less than an ABI - an
alternative binary interface. Linux programs "communicate" through
this interface instead of FreeBSD's default one.
Of course, there *are* security implications, as on Linux. Security
limits are given by the FreeBSD infrastructure (e. g. "Flash" based
malware trying to access system files -> no; defective "Flash"
implementation causing a memory leak -> possible).
I don't use "Flash" anymore so I can't be more specific. Last time
I tried it worked nearly flawlessly with Firefox.
A personal note: Sometimes, I found that Linux programs ran faster
on FreeBSD Linux ABI than on native Linux, but as I'm not a regular
Linux user, my opinion isn't worth more than 2 cent. :-)
Happy FreeBSD user since 4.0
