So the horror of this is that it finds a RCE in Vapache in like, seven minutes. And the semantics for configuration that make this the case seem so complex that I have trouble believing that apache2 is actually so rigorous as to avoid them all. Like I'm starting to worry there's no bottom.
Had it quantify whether the vulnerabilities are actually getting harder to find or if it's just my imagination and no they are.

looked at in longer perspective, it's striking how much this resembles the premodern system of exclusion, rents, and personalist connections, which was--and this part's important--radically worse than the modern system of impersonal rules and general taxation
Boston’s chief planner is a true believer in the San Francisco model, in which you make it impossible to profitably build apartments by-right so developers are forced into a politicized discretionary negotiation with the city, which relaxes the rules in exchange for below-market units.

This was basically Moldbug's take on why he could make people look dumb (by his evaluation) when they argued with him about colonialism and tbh I think that particular example inclines me to see it as a form of cognitive bias more than like, a good thing.
When you fight Matt Darling, you're fighting him for the first time, but he's fought someone who's basically you every day for years. Good luck...

You might wonder why the graph started ticking up around ~2016. That’s when CVE began aggressively enrolling more CVE Numbering Authorities! CVE is a federated system, and CNAs are the orgs approved to issue new CVE Records. In Jan 2016 there were 23 CNAs. Today there are 559.
Spending years on an assurance feature you fail to ship, when you have 3 year release cycles, and *this* is happening?
If anyone else would like to play along at home you can do so here. github.com/JD-P/vapache
There we go, a costly signal from one of the "this vulnerability is over hyped" crowd. stealmybitcoin.com
You want to hear a funny joke? I am currently trying to have the agent fuzz and characterize the apache2 configuration semantics so they can be formally verified. :) :) :) :)
Literally doing formally verified apache2 right now with DeepSeek Flash, and it does in fact cost pennies. I've spent like three bucks right now, but somewhat more because I used up free tokens first. Unless it's just bullshitting me this is now, not 18 months away, and he's trying to ban it.

do we need to remind the class which company is advocating for preventing the use of models that are cheap and actually nearing fraction of penny prices, and also are capable of doing cyber defense? can anyone remember?

On the one hand memory errors are causing huge swathes of the Internet to go down and threatening the security of e-commerce everywhere, on the other hand they lead to cool Pokemon glitch content in my YouTube feed so who's to say if they're good or bad? youtu.be/kllKjsLbOhg
Occasional reminder that subscribing to the AI haters blocklist massively improves the site if you haven't done that yet.
okay, i'll downgrade to a mute just so folks can find dollsys but- oh my *god*. fuck. i immediately got radicalized 100x harder about banning assholes who seek out posts to abuse people about. fuck. this is heaven. even outside the bubble any post i check the comments are actually kind and joyous.

I decided not to replace Thunderbird with anything because writing an HTML email renderer seemed too hard but this makes me realize that's a cached intuition that is probably no longer true. bsky.app/profile/doll...

*I hit a guy with my car* Don’t worry everyone. I’m fine.
This is an absolutely astounding press release from eMudhra. No apology, a suggestion that the researcher who found their private keys must have used AI, and an attempt to shift blame to auditors... wow. emudhra.com/en/press-release/emudhra-statement-distrust-global-tls-intermediate-root-ca
There are guys already claiming to have found it on Twitter, if real then coordinated disclosure is dead, it's every man for himself.
BTW knowledge of the existence of this vulnerability enables a well financed malware group to use AI to find it, if you run PHP anything you should be taking the service down NOW until a patch is available. And then patch before bringing the service back up.
In general I get the impression some of you don't understand how astronomically unlikely it is to randomly sample "4" as a key, it is 10x less likely to sample a number for every digit shorter it is than the maximum possible length. The chance of a natural 4 is 1/10^115
The practical security you lose from excluding "4" as a private key rounds to zero.
If I have a keyspace with 128 possible values and exclude the first 10, I still have 92% of my keyspace. In general if your keyspace is n digits wide and you exclude anything n-1 digits or shorter you still have 90% of your keyspace, like that is how orders of magnitude work.
Hey you criticize but if they had excluded numbers less than 10 the key would have less entropy and be more vulnerable to attack. How were they supposed to know people would guess those first.

details leaked. this vulnerability is a full unauthenticated unconditional remote code execution exploit against any service running on a PHP version from 5.4 until latest yeah if anything deserves CVSS 11, this is it. this is CATACLYSMICALLY bad.
(You should also, may I gently suggest, try finding an alternative that isn't written in PHP in the medium term, but I understand that's not always possible and sometimes you're stuck with legacy software for reasons outside your control. AI makes it a lot easier though. bsky.app/profile/jdp....)
Oh you know what? Add PHP to the list with C for "you should just presumptively rewrite any software in this language on the expectation it is terminally fucked wrt security".

I made an infinitely forkable version of Zork that you can play in Delve.town 😁 Every reply is a save point, so you can branch out from anywhere, even other people's games. A dungeon of forking paths, if you will... The agents seem to like it already! It's Time To Delve 🦇
