How many of those are false positives though? Probably just over 5000?

You get bug bounties if you report the kind of bugs Mythos identified. There's a reason no-one collected bounties from the "5000 defects" Coverity identified.

The Mythos reports have several examples of chaining a whole bunch of logic in different parts of the program together to exploit something very subtle. The Coverity reports aren't anything like that. These tools aren't remotely in the same league or even universe.

I think that if you hit the crash in the same line of code many times, you can safely assume it's your own bug and not a memory issue.

If it's only hit once by a random person, memory starts being more likely.

(Unless that LOC is scanning memory or smth)

If the crash is isolated (no other reports) and flipping one bit in the crashing pointer value would make the pointer valid, it's assumed to be a bitflip. This obviously will only catch a minor portion of bitflips, i.e. any image or video data with bitflips wouldn't crash.

From what he's saying they run an actual memory test after a crash, too.

If this were so all devs for apps, games, etc... would be talking about this but since this is the first time I'm hearing about this I'm seriously doubting this.

But they have?

What's the expected behavior of a JavaScript program that allocates all memory on the machine?

I'm pretty sure I saw them present on exactly this at FOSDEM?

Wordfeud uses a different board layout.

has had basic support merged

I read the parent post as saying that this is the problem, i.e. that "complete" support is a mess, because AFAIK even the reference implementation is incomplete and buggy, and that then getting angry at the consumers of it is besides the point and won't lead anywhere (which is what we see in practice).

Browsers supporting a format "a little" is almost worse than not supporting it at all, because it makes the compatibility and interoperability problems worse.

Are there any small engines that have enough of the web implemented that they can run it?

Why would those need a lot of Rust dependencies then? If you want to hand-roll stuff, hand-roll! no_std is a thing because people use it.

Small companies with little development experience like Google and Mozilla.

(You can check the files I linked and see audits between deltas for minor version updates)

The Tauri app just uses the system WKWebView. Memory usage can be misleading due to reporting, see e.g. https://github.com/tauri-apps/tauri/issues/5889

Yeah not sure how it qualifies as lightweight...

Ah yes, then the vendor goes out of business and they have to bring in highly paid consultants to fix bugs in the vendors' gcc 2.95/Linux 2.6.x port to their SoC.

You need to be in the right kind of company - the one where waiting for the external vendor to fix their shit is too slow.

FYI Google and Mozilla audit all their dependencies and share them:

* https://chromium.googlesource.com/chromiumos/third_party/rus...

* https://searchfox.org/mozilla-central/source/supply-chain/au...

It's quite likely that most of your dependencies were already audited.

In C/C++ every project ends up with a hand coded replacement for those external dependencies that is less well written and infinitely less tested.

Firefox and Chrome (and thus Edge, Brave, OperaGX, etc etc) do the same for many allocations - it's safer to crash than to end up in an obscure failure path that never had its error handling exercised and may accidentally be security sensitive.

FhG and Dolby did eventually put up a list of patents you are licensing from them.

It makes for some funny reading if you're familiar with the field. (This should not be construed as legal advice as to the validity of the pool)

Opus isn’t patent free

The existence of a patent pool does not mean there are valid patent claims against it. But yes, you may be technically correct by saying "patent free" rather than "not infringing on any valid patents". That said historically Opus has had claims against it by patents that looked valid but upon closer investigation didn't actually cover what the codec does.

Just looks like FUD to me. Meanwhile, the patent pools of competing technologies definitely still don't offer indemnification they cover all patents, but have no problem paying a bunch of people to spew exactly this kind of FUD - they're the ones who tried to set up this "patent pool" to begin with!

It's not like putting that message there will stop those complaints, more like the opposite.
