Google To Auto-Migrate Some Users To 64-bit Chrome 96

Posted by msmash from the hmm dept.
Google says it will automatically upgrade the version of Chrome that some Windows users are running, in what it describes as a bet to improve stability, performance, and security. From a report on ZDNet: In a blog post on Tuesday, the search engine giant explained that Chrome users running 64-bit Windows with 4GB or more of memory will be automatically migrated to the 64-bit version of Chrome if they are running the 32-bit version.

      That is why since long ago I inconsciently start all google queries with "allintext:" to try to cut the google 'relevant' crap.

    What does 32 vs 64 bit have to do with security? I'm genuinely curious... It seems as if they are claiming their 32-bit users, or those without 4GB of RAM are somehow inherently less secure. That seems like marketing nonsense to me.

    Of course this wouldn't even be an issue if Windows wasn't such a giant piece of garbage that it's taken this long to get a mainstream 64-bit operating system and applications. I've been running a 64-bit build of Firefox on Linux since, what, 2004?

      Address space layout randomization. To make it harder for buffer-related exploits to actually start executing arbitrary code, the memory pages get shuffled around at startup so all the memory addresses are different each time. This still works with a 32-bit address space but there's less total space to use, so with some brute force (eg. really long NOP slides) you can overcome ASLR. With a 64-bit address space, odds are a random jump won't even hit a valid memory address.

More importantly it's vastly larger than the addressable RAM in your computer... and a 32-bit address space is actually smaller than the amount of RAM in many (most?) computers today, since 32 bits can only address 4 GiB.

      What does 32 vs 64 bit have to do with security? I'm genuinely curious...

      What is has to do is that the architecture that brought 64bits (AMD64), also brought several security features (like NX bit) among others.

      32bits software might be targeting architecture that predate the NX bit (e.g.: if you still have an old 32bits .EXE that dates back from the Pentium 4 era, it might be writing to and executing from the same memory area), and perhaps Windows could theoretically not enable NX for 32bits legacy software on these grounds? (to avoid to break old 32bits software ?)
      By accelerating the deprecation of 32bits software, they might try to deprecate the non-NX software ?
      (That is pure speculation on my part. I have not enough experience with Windows)

      (register vs. stack pressure is also different between the 2 architecture. AMD64, in addition to 64bits, also brought twice the number of registers. meaning that more things can be kept on CPU and less needs to be written to the stack. Which could mean less potential candidate in case of stack smashing exploit. But I'm really going on a limb here. Return address is way more interesting to abuse in this case than register value.
      It's definitely less probable reason than NX).

      I doubt that software would be affected easily by any other difference between the two
      (e.g.: warp around at different values, 0x7fffffff vs. 0x7fffffffffffffff
      That is highly unlikely : win64 is a LLP64 platform - all integers are still 32bits (both int and long), unless explicitely required (long long, hence the LL) and thus all value still wrap similarily between same source code software compiled for 32bits and 64bits.
      only pointers are promoted to 64bits (hence the P) and thus only point math would wrap differently)

    Google earth is only Google application I ever wanted a 64-bit version for because I'm tired of seeing it hit 2GB process limit and promptly crash. Apparently checking memory is too hard.

    Unless an app actually legitimately requires more than the 32-bit process limit I prefer 32-bit apps for the following reasons:

    1. Slightly less memory overhead /w 32-bit address space.

    2. No matter what a user process won't go haywire and run your system out of memory leaving your entire system in virtual memory swap hell.

    On windows 64-bit for 64-bit's sake in the absence of a legitimate need to address more memory (A web browser does not constitute a legitimate need) simply because 64 is a higher number than 32 is a fruitless enterprise. All of the technobabble differences are a wash with no tangible benefit to the end user.
