If only we could come up with a way to manage memory automatically. Alas, one can only dream.
I'm pretty sure this class of problem would exist in GC'd environments too unless they're configured to abort on OOM, in which case you'd still be dealing with denial-of-service.
In some environments OOM is a trappable exception, so it's possible that incorrectly authored code would trap the OOM and 'recover' with partially initialized data sitting on the heap. Hopefully it's a memory-safe language so that partially initialized data isn't RCE...
Just pulled the new matomo that was published on dockerhub 26 minutes ago, thinking it has the patched PHP version:

What would happen if the director suddenly gets sick or decide not to come to work anymore? A lot of people assume that humans are reliable, they are not.
Exactly: limiting access is fine, lack of contingencies is not.
Some systems and services still only allow for one owner though (I'm not going to name names), which can be a big problem when MFA is mandated. From what the poster I responded to said, I'd be very surprised if that were the case for them though - just slightly daft policy.
My team rotates 1 sacrificial member every week to be on call with prod k8s access. It limits who can just push things to prod at any given time while making sure everyone on the team has experience. If someone is out sick or on vacation we do time trading, it works out for everyone.
One of my first boss called it the bus factor, not sure where the term comes from. What's the minimum number that need to get hit by a bus before it's impossible to keep things running. He used to say "you always have some bus factor, but it should never be one unless you're alone, otherwise you deserve whatever crap is going to rain on you someday".
I've found that to be incredibly true in my career.
With AI agents, I've been using sites/services that are bot friendly and don't require MFA.
Not everything needs hyper security. Heck, I've given AI access to spend money on websites and my only restriction is that the websites limit the daily spend(website side... Although I guess a rogue AI could have changed it... )
how does Docker not yet have a new, official PHP image ready, given such a big heads up? https://hub.docker.com/_/php Nuts this wasn't ready to flip on at :00 (or even earlier given the PoC exploit and even the official PHP fixes were out well before). Now we are 27 minutes past due.
It would not be easy (or reasonable) to take a public build like that private to build a 'secret' image version, and I'm not sure GitHub even has the capability to do that. I would not trust a build pushed to Docker Hub separate from the established / public / auditable process they have in place.
All dependent (official) images need to go through the same process, so that makes it fairly problematic, and I think Docker needs to take a look at it for the future.

I'm starting to suspect that they actually got the notice the same time we did, because if they got the patches there should be no reason it wasn't already built and ready to go (unless they're scared that "our build servers are public and everyone will know" so they literally held everything off until the release which seems so counterproductive as to be ... well, open-source silliness).
If you mean docker official images, it's just the "community" maintaining it, eg "some dudes". By no means should you consider it a mechanism to get timely security updates, I've seen horrible lag on that before.
Most of docker is like this. Images provided by volunteers, and not related to the project. Using docker images you don't maintain yourself, and at least don't upgrade yourself, is not the best recipe for security.
There are different approaches and it all comes down to who you trust. I don't think there's universal answer. If you have money, find image provider who's serious about security and hopefully they'll provide patches images quickly. Otherwise using Debian packages is a good default I think.
Honestly I don't even understand why so many docker images prefer to build software from sources, rather than just installing them from debian repositories.
And if you're using a docker package it's often JUST BECAUSE the host Debian/Ubuntu server is out of date for things you need, and Docker's the easiest way to "patch" that.
Why is the description of "RCE via OOM corruption" mentioning all these settings like memory_limit, post_max_size, max_input_nesting_level etc under "Mitigation" but not blocking multipart requests? Isn't that a solution?
The description of the vurnurability "Several multipart parsing problems" makes it sound like it is?
last I looked, automatic updates for wordpress meant letting the web server write to the document root, which may be on the same level of negligence as not updating quickly.
Plus, wordpress updating isn't going to help you upgrade php.

There are rare occasions when circumstances are more important than preserving an "EOL" designation. This appears to be one of those times where "official" centralized patches really should be made available for at least PHP5.6 and PHP7.4, and perhaps even 5.5 and all of 7.x. They're not covering themselves in glory by refusing.
Yes and no, you have two setup, you're on LTS, it will be backported (done as I write than on Debian), not on LTS and you already have hundreds of unsafe stuff running anyway so it's just one more to the pile.
Yeah, I have a legacy site that is popular and doesn't make money with some outdated version of PHP that will not update. Maybe I need to install OpenClaw on it.
But yeah, with AI agents, I don't really understand the purpose anymore. Legacy WordPress or laravel sites?
If those place at using a LTS release of their OSes they will be patched quickly (Debian already has). If they're not, they're already screwed by a lot more than just PHP I guess.
PHP runs literally half the web. Half the web will not apply this patch in any reasonable amount of time (a huge portion will never). This is going to be absolutely catastrophic.
The union of hosters which will not update to this patch, and users who have not updated to the past 283762 CVE is literally the same circle. I think that maybe a couple new not infected machines will get infected with a cryptominer - the rest will just get one new miner fighting for resources
They should probably invent some sort of Crypto Miner Communication Protocol (CMPC) that will make the process easier for all miners out there. Let's hope most are not bad actor crypto miners who ignore the protocol though, we should strive for more good actor crypto miners.
So if I wanted to build a botnet, then it would be very easy ;).
Infiltrate vulnerable PHP sites. Install backdoor(s). Secure root access. Patch PHP to lock out script kiddies. Let it sit dormant until you need to launch attack

I guess they were planning an update for today, for a moment the 8.2.35 threw me, but .35 is patched on 8.2, unpatched on 8.3 :)If you need Docker to run PHP software you're beyond any help already.
Yeah, I really enjoyed messing with php.ini back in the day! Setting it juuuust right for every different project on my dear pet.
FML. Can't get in to update our servers because of MFA and our director, who gets the codes, isn't in
Great example of performative enterprise security practice that contributes to degraded security posture, I suppose. Best of luck.

This is where tooling like 1Password or Apple Keychain that lets you "share" MFA comes into play.
It doesn't allow sharing SMS, email or proprietary app based MFA.

Yes, it's embarrassing for Docker. Makes me wish I still had the classic LAMP stack.
A PR was posted within a minute or two of PHP's source code update. Then within a minute of the PR's CI job completing, it was merged, and the build took a while but is now complete: https://github.com/docker-library/php/actions/runs/396158697...

All dependent (official) images need to go through the same process, so that makes it fairly problematic, and I think Docker needs to take a look at it for the future.
It would however be reasonable to expect a maintainer to be available to start the CI faster than 30 minutes after the PR was created.
Docker have been carrying a broken python build for months.
they are wanting people to pay for the hardened version.
Does anyone know the ETA on the official php:* docker images? I think they only released patched 8.6 RC containers for now.
The PR with the update is here: https://github.com/docker-library/php/pull/1694
Looks like we need to be patient:

one of the more entertaining PRs I've seen
Enough spam comments to create a huge blacklist of misbehaving github users.
Might have to wait for the github outage to be resolved first :D https://www.githubstatus.com/
How about the Ondrej PPA repos for Ubuntu?
They're updated for all versions
While the patches are being merged for the official docker images, perfect time for a github outage! https://downdetector.com/status/github/
Still no release for Ubuntu... They are already half an hour late. Debian got the patch almost immediately...
The builds are there: https://launchpad.net/ubuntu/+source/php8.5/8.5.9-0ubuntu2.1
https://launchpad.net/ubuntu/+source/php8.3/8.3.6-0ubuntu0.2...
https://launchpad.net/ubuntu/+source/php8.1/8.1.2-1ubuntu2.2...
but nothing shipped yet by their mirrors, unlike debian.
even the security.ubuntu.com mirror doesn't have it yet
Now they have finally shipped it.
Ubuntu probably started working on a rust based replacement instead: rphp.
Why are they so slow. My Archlinux is already updated, but I still have to wait because of this.
curl -fsSL https://packages.sury.org/php/README.txt | bash
This adds Ondřej Surý's PPA to your system so you can upgrade the packages.
Just make sure to have the ca-certificates fixes already...
Why do people still use Ubuntu?
They gave away CDs 20 years ago for free. Cooool.
Fedora is best for desktop.
Debian for servers that never need updates (but I even use Fedora for server now adays)
if it makes you feel any better, the official dockerhub images aren't ready yet either.
They had almost a full day to prepare for this...
I'm starting to suspect that they actually got the notice the same time we did, because if they got the patches there should be no reason it wasn't already built and ready to go (unless they're scared that "our build servers are public and everyone will know" so they literally held everything off until the release which seems so counterproductive as to be ... well, open-source silliness).

(It's pretty trivial to build your own)
I wasn't aware of that. So I guess it's generally better to just use plain debian images and just install the required packages with apt.
There are different approaches and it all comes down to who you trust. I don't think there's universal answer. If you have money, find image provider who's serious about security and hopefully they'll provide patches images quickly. Otherwise using Debian packages is a good default I think.
Honestly I don't even understand why so many docker images prefer to build software from sources, rather than just installing them from debian repositories.
> I don't even understand why so many docker images prefer to build software from sources, rather than just installing them from debian repositories
Because Debian uses older relases and a lot of custom patches. One example: Nodejs still doesn't have Typescript support in the Debian packages.
Distribution packages vs. official build from source has both pros and cons.
And if you're using a docker package it's often JUST BECAUSE the host Debian/Ubuntu server is out of date for things you need, and Docker's the easiest way to "patch" that.
welp, I guess I should have done my research into what "docker official images" actually means.
Debian has had the patch for days, as have other main distros, and tested and prepared the release. That's why it was instant.
Unclear why Ubuntu is lagging.

PHP 7 hasn’t received an update since 2022 when it went EOL.
EDIT: looks like there are backports though
There are backports already.
Debian has a new build of 7.4 at least.
Not out on Ubuntu 20.04 yet, but sometimes they are a little slower. Hopefully should be posted later today.
