OpenSUpdater Malware Hides Reflective Loader Inside Recompiled 7-Zip SFX Installers

If you're heading to the #OpenSSL conf in Prague Oct 13-15 make sure you chase down @jimfuller and unload him of a few #curl stickers.

He's going to be our official distributor there. You can have your fix from him. For free. You know you need one. Or two.

#curl 8.23.0-rc2 is here. The second release candidate: https://curl.se/rc/

Do not use release candidates in production. They are work in progress. Use them for testing and verification only. Use actual releases in production.

When we announce over 20 new #curl CVEs on October 14, you will learn that every single one of them were found by clever humans using harnesses powered by AI models. Every. Single. One.

The holy trinity of modern vulnerability research.

Another security person said this about #curl in an email to me the other day:

"Maybe we're really headed towards curl being the most informally verified library in existence (although it seems to me it likely already is)."

Dan Lorenc at Chainguard posted this statement about #curl on LinkedIn...

We put curl 8.22.0 through an eight-and-a-half-hour automated tree search, about 4,100 tool calls and roughly 190 million tokens of model work (the vast majority cache reads), aimed only at High and Critical outcomes: memory safety on an ASan build across the HTTP/1, HTTP/2, HTTP/3, WebSocket, FTP, IMAP, POP3, SMTP, SMB, LDAP, cookie, and NTLM/Digest/Negotiate parsers under tens of thousands of hostile server responses, plus integrity hunts for TLS verification bypass under an on-path attacker,
STARTTLS and 1implicit-TLS downgrade, cross-handle response confusion, CONNECT tunnel handling, credential leakage through redirects, file writes outside the output directory, and Alt-Svc and HSTS guarantees. Thirty-one lines of attack closed clean with no sanitizer report and no verification
bypass; all that surfaced were three Medium-class edges, one of which the curl team had already fixed on master days before we looked. That outcome is a credit to the project: years of continuous fuzzing, the maintainers' own audits, and a codebase where every server-controlled length is bounded
before use left a persistent automated adversary with nowhere to go. Congratulations to the curl team, and thanks for making our negative result so thoroughly earned.

One note on the token figure: the run log records usage for only about 400 of the turns (18.6 million tokens, 46,500 per turn on average), so the 190 million is that average scaled to the 4,103 tool-call turns.

we received a list with ~160 #curl bugs (explicitly *not* vulns) from Aisle that now sits in a private repo for us to work through over time. Things they fell over while scanning for issues. Nothing major, but smaller things we might want to polish.

I'll do a free webinar on Thursday about our long term support #curl branches we call rock-solid curl:

A health check of mine kept calling a server down while the server answered 200 the whole time. curl exits 18 when the body is cut off mid-transfer, and I read any non-zero exit as no response. Two different questions, one variable.

Please take it for a spin and double-check that it works just as smooth as you would expect.

I had a look at the “project number of CVEs” that we estimated back at #curl up in late May. We then said it could end up at 55 by the end of the year. As we now already have published 45 and there are (at least) 20 coming, we have certainly exceeded those projections. The question is now rather […]
