Samba - announcement & version

Hello, please allow one silly question: my samba version is "samba-2.2.7a-0" on a Suse 7.3 is this version affected too? I.E. do i have to install samba-2.2.1a-213.i386.rpm as it is said in the Suse Annoucement ? Thank you, Andreas (how is a bit confused by the Version numbers)
