DieHard

Has anyone else heard of this program? Anyone try it? I think I'll give it a go. Although: "one caveat is that DieHard noticeably increases memory usage", I'm curious none the less.

The Windows version only works for Firefox yet.
Linux version for all applications.
Memory increase 50-75 %

Well the installation went without a hitch. Took only seconds. So far, no apparent conflicts with any other programs. You can enable/disable protection for Firefox. You have to restart FF to both enable and disable. Diehard shows no process in Task Manager or Process Explorer while it's active. I did find two dlls loaded with FF while Diehard was active:

Diehard-system.dll
madCHook.dll

The only thing I can report on so far is the memory usage.
When Diehard is not enabled FF's mem usage is around 31MB.
With Diehard enabled, FF's mem did go as high as 121MB. Quite a jump.
There was no elevated memory usage in any other process, only Firefox.
As far as protection, I can't really say right now.

This is what Emery Berger writes about Diehard's protection:
"DieHard eliminates — or greatly reduces the likelihood of — a class of bugs and security vulnerabilities called memory errors. DieHard prevents certain kinds of errors from happening at all. It also reduces the probability that a bug will have any effect at all. DieHard works by randomly locating program objects far apart from each other in memory. This scattering of memory objects all over memory not only makes some errors unlikely to happen, it also makes it virtually impossible for a hacker to know where vulnerable parts of the program's data are. This thwarts a wide class of exploits."

Yeah right, in order to make my system more stable I´m going to settle for a 50 to 75 % increase in RAM usage. Why do they not just integrate this kind of tech in the OS? Oh wait, probably because of the higher RAM usage issue?
