From the CP newsletter about how a new language will fix all problems that come from C++
Swift the best choice to succeed C++, Apple says | InfoWorld[^]
For a few years I was a principle security reviewer for a financial application. It wasn't written in C++ but that certainly didn't make me think that it wasn't possible to introduce security problems.
And I looked up top security problems in 2023. I only got above halfway down the list but I didn't see any that seemed to be caused by C++ pointer errors.
Qualys Survey of Top 10 Exploited Vulnerabilities in 2023 | Qualys Security Blog[^]
Matter of fact when I was a security reviewer I got to see a private study produced by a company that made quite a bit of money from cleaning up security problems that companies had.
And in that study something like 90% of the problems were caused by internal bad actors.
Rather pointless to obsess about whether your pointers are safe when the CEO is using internationally set up companies to ship fake orders and thus prop up the companies stock (real case.)

Back when I was a teenager and the Internet was a fresh thing to most people I spent my time getting into systems I didn't belong in.
And most of the time I got there by using buffer overrun attacks on services that should have never been Internet facing to begin with, like a network print daemon (citing a specific example that allowed me to identd on efnet as freshmeat@usda.gov  )
My point is, this used to be common, at least in the wild west days of the Internet, so I wonder how much of the fact that it doesn't seem to be so common now has to do with better practices, better libraries, and such in C and C++. For example, Microsoft produced a bunch augmented functions to the C runtimes that take lengths which they check so you can't overrun them. Things like strcat_s? and stuff. I don't really use them because I don't do a lot of C++ on Microsoft's compiler, but it made me think of that.
Also, probably less services are written in C or C++ now that machines are cheaper and faster.

I don't use the strcat_s family of functions either. I find that strncpy, strncat, and snprintf handle things quite well.

TBH, so do I. If I was pressed I probably couldn't tell you what the actual benefit of the _s functions are - only what MS presented them as.

I believe their claim is they use sizes that are automatic so you can't "lie" to them. My view is this is C/C++ and I trust myself. I wouldn't use the language if I didn't.

You'd be surprissed how many services are "internet" facing even though they should never be... not even basic security considered. Recently had an incident where a RDP connection was possible to a server holding / running finicial data for multiple companies... not even a FW or anything inbetween... scary sometimes

I'm not surprised.
But you have understand that in 1994, almost everyone was vulnerable.
It's relative.

I would say that you have a category error here. One must divide the security breaches into unauthorized access, and authorized access to perform unauthorized actions. The first encompasses all "hacking" attempts (buffer overruns, SQL injection, etc. etc.), while the second encompasses the "inside jobs".
Secure languages are an attempt to mitigate "hacking". Proper procedures are one way to mitigate "inside jobs" and designing them is at least as difficult as designing a secure language.
C++ already has the neccesary mechanisms for producing robust code - unique_ptr<>, shared_ptr<>, string, vector, etc. The problem IMO is the legacy code ported from C, and new code that uses ordinary pointers and buffers in a misguided attempt at optimization.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

The problem is also code written before C++11, when those pointers became available. It won't get retrofitted unless it has problems attributable to pointers, which it typically won't given the time it's had to soak. For new code, I think failing to use the things you mentioned is less a case of misguided optimization and more one of ignorance on the part of those who never progressed beyond the pure C way of doing things.

It's just too easy to make a serious mistake even if you do know what you are doing and are extremely good at it. Meanwhile, the penalty for near any such failure is near inevitably RCE or privilege elevation with both basically throwing the doors wide open for the barbarians at the gates.
It's also "just how things are done", using pointers and pointer arithmetic. Maybe you can make a performance argument in a very few cases. (Why are they pythoning all the ML stuff instead of C++?) Mostly though, we aren't seeing superior products as a result, but inferior ones, not in terms of performance, but security. And it's just not worth it anymore to use these unless you just don't have a choice. The situations where that holds true are shrinking fast. They'll be gone inside a decade when I think it will be totally reasonable to expect something like a .NET-on-chip and other similar such inroading into embedded development.

If you're looking at technical issues leading to security issues, then null-terminated buffers are the number one problem, followed by use after free and then reading uninitialized buffers.
If you're looking at all sources of security issues, people are by far the number one cause of security incidents.

I was writing a lounge entry and the front door got slammed on me.
I tried getting to CP from two different networks so I'm pretty sure it weren't just me.
Ya'all saw that too, right?
I took a snapshot of it.
Here's what I saw[^] and it was instant.

Wow, not even the stylized 404 error page. Something really choked. I didn't see anything, FWIW

I believe it was around 5:45pm Eastern Standard Time on thursday, June 13.
I tried to ping the site to and couldn't get anything -- and it was such a huge disconnect that I thought it looked like a DNS issue.
I remoted to my work computer -- in a geographically different location (another city from me) and on an entirely different ISP and I got the same error from browser : 404.
|
|
|
|

I saw that. I guess a 404 is just enough to tell Down Detector and other such sites that "something" is coming back, so they all claimed it was up...
|
|
|
|
|
That's interesting, because for me it was instaneous and quite harsh: I mean I couldn't even ping codeproject.com at that time. It was literally like someone slammed the door on me.
I tried from an entirely different network and got the same thing.
Glad someone else confirmed seeing it to. 
|
|
|
|
|
Oh it was instantaneous, nothing spent any time trying to resolve anything and then timing out. The 404 response was pretty much immediate.
I'd be curious to read any post-portem Chris would be willing to share.

Here's an additionally interesting thing: Today my work's ISP is having major issues.
Can't even ping our web site at this time.
Here at home and other coworkers spread through-out cities are working fine but none of us can get to our work machines via RDP and our company is virtually cut off from Internet.
I pinged our web site and got: Temporary failure in name resolution.
Oh, and we can't get to our company outlook, but we can all still chat via MS Teams.

Woke at 04:00, shower, coffee, toast, emails.
Then the ironing to get out of the way before dropping the car off for a service and have new brake disks fitted all round - I've got 20 mins before Timbo is due to pick me up, so I'll do a quick supermarket run to get mouthwash (since I opened the last new bottle just before bed last night) and a few odds and ends.
Walk out of the supermarket and the phone goes - Rich needs a favour. Sure, what do you need? "Can you drive me to A&E, I think I've broken my foot." Ah. No car - have you still got Gills car key (his wife went on holiday in sunny climes yesterday)? Yes. OK, I'll be home ASAP and get you off down there. Ring Timbo to see if I can hurry him up, and the first thing he says is "Can you do me a favour?" 
His neighbour (a drug addict) has had a stroke, so his (psycho) wife is down at the local A&E with him, and he's babysitting the two girls* but Timbo's wife is due at physiotherapy at 11, could I take her? Explain the car problem, the Rich problem but say I'll do what I can. Finally he turns up and I get home, grab Rich, he grabs his fishing gear so he can tie some flies while he's waiting to be seen because he's going on a three day fishing trip tomorrow, I suggest his phone and charger and off we go - to a further away hospital than the addict because his wife's daughter is a doctor and they have a shorter waiting list.
Surprisingly quickly "how to drive a manual" comes back to me - it's been nearly two years since I switched to auto - and I drop him off, get back home to look after their dogs just in time to swap to Timbo's car and load up Eryl for her physio and off we go. I wait outside, listening to an audiobook and then take her home. As I'm reversing into their drive (which is a complicated job in an unfamiliar car) the phone rings - it's Rich who has been processed, could I collect him? Swap back to Gill's Fiat (a willing little hybrid, but the second slowest car I've ever driven and with the build quality you expect from Italian cars) and drive back to the hospital to collect Rich who has indeed broken his foot and has a large boot on which means he can't go fishing tomorrow. He's not a happy bunny.
Finally get home and the cat is furious because it's been eight hours since he ate his breakfast and I should know better than that ... 
And one of my jobs today was to set up a new set of cat food for him as he's a picky little toad and I have to feed him different meat / manufacturer for each meal or he goes off them and will never eat them again. So I've got to do that before I can feed him which isn't his idea at all.
Busy day. And it's not over yet.
* And Timbo's as good with kids as Josef Fritzl but that's their problem**
