Flash plugin of debian vulnerable?

I run Debian wheezy with Iceweasel as browser and have installed the Flash plugin similar to this description. Today I read that not only Flash on Windows and Mac also Adobe Flash Player 11.2.202.350 and earlier versions for Linux are vulnerable to exploitation. When checking my version in Iceweasel > Tools > Add-ons I was surprised to see that it is an older version, even though I did all upgrades with apt-get.

Does Debian provide updates for the Iceweasel plugin Flash at all? Are they not automatically provided? Do I always have to manually update the plugin?
