From what I hear, if you're the only one using your computer, you don't really have anything to worry about.

In short, this vulnerability allows any process to read the private
memory of any other process, including unencrypted passwords, if any.
If you are the only user of your computer, all the processes are yours,
and there is nothing to worry about. If you are using a shared
computer, you might want to avoid running programs like password safes
that might keep unencrypted passwords in memory. Or you can simply not
worry about it.
