The PR with the update is here: https://github.com/docker-library/php/pull/1694

Looks like we need to be patient:

> Why is this not merged yet?

> I'm not a maintainer and can not merge this. Please wait until a maintainer has come around to look into this.

> This is merged, but I cannot find the image?

> After this PR has been merged, more steps are to be taken, including an upstream merge on docker-library/official-images and subsequent image builds. For a full description of the timeline, please refer to docker-library/faq#an-images-source-changed-in-git-now-what.

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?

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.

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.

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.

bartread 1 hour ago | parent

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.

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.

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).

b112 1 hour ago | parent

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.

(It's pretty trivial to build your own)

andix 1 hour ago | parent

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.

vbezhenar 1 hour ago | parent

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.

andix 56 minutes ago | parent

> 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.

bombcar 50 minutes ago | parent

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.

dmtroyer 1 hour ago | parent

welp, I guess I should have done my research into what "docker official images" actually means.

b112 1 hour ago | parent

Debian has had the patch for days, as have other main distros, and tested and prepared the release. That's why it was instant.

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.

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.

> out-of-memory handling can interrupt PHP while internal request data is only partially initialized. Request cleanup may then treat the invalid data as valid.

If only we could come up with a way to manage memory automatically. Alas, one can only dream.

kg 48 minutes ago | parent

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...

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...

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.

This is just the first step. See here for the full process: https://github.com/docker-library/faq#an-images-source-chang...
