[TYPO3] Typo3 version and rtehtmlarea in security bulletin 20061220-1

[Santiago Tejero]

Hello,

We've a Typo3 3.8.1 installation and we're using rtehtmlarea 1.2.1. On the security bulletin "TYPO3-20061220-1: Remote Command Execution in TYPO3" about the vulnerability of rtehtmlarea 1.2.0 + aspell
	http://typo3.org/teams/security/security-bulletins/typo3-20061220-1/ 
in the solution page it says on one of the points:
	"A) Update your TYPO3 core system to the latest version"

Does this means that we need to update our Typo 3.8.1 to Typo 4.0.x or we're fine with our upgraded rtehtmlarea 1.2.1 on Typo3 3.8.1?

Thanks!
