I think what the press release was try to say is that the buffer overflows that break x86 boxes wont work on a PPC box. This is not the same thing as saying, PPC doesnt have buffer overflows, just that, you have to do it a lot differently.
Much of the office and network IT infrastructure in use today is x86-based,” explained Buck. “The Guardian runs on a different processor platform and is not as susceptible to the common buffer overflows that are the main entry point for security breaches.”
"x86-based" exploids wont work on PPCs. This is commensence but for some reason they wanted to spell it out. I guess everyone doesnt know the differences between the two platforms. But the point is, in an x86 world people are going to assume that you'r box is x86 and if they try to exploit it, they're not going to succseed. They only way they will is if they know the box is PPC and they change the way they exploit the box. Thats how i read it anyway!
