Samba can also expose your CUPS configured printers too so it's not just 631/tcp to be watchful of.
That's not typically the default but we're talking about something that is fundamentally designed to be a server & queue manager for others on the network. By default, cupsd (the actual server & queue manager) may well be bound to localhost, with browsing set to no and various IPP API endpoints restricted with location ACLs but all of these can and are changed for various reasons (witness 631/tcp being open).
We had a short look at the buffer overflow found by fuzzing `process_browse_data` to determine its exploitability. Conclusion: this bug alone won't give you RCE, or even an info leak.
Here's my quick and dirty PoC for the CUPS vulns. I wrote it after spotting the patches in the public CUPS repo. As always, expect CTF-quality code :D
Finally I got myself to write a script to generate documentation for #Ghidra - now I host the latest info about 11.2, including but not limited to:
I took this opportunity to redo the directory structure that broke most search engine links, sorry about that (this will improve with time ofc)!
Normal authors: release book to the public early in the week, with much fanfare.

If you wanna take action after, we've got a list of things to do at https://www.battleforlibraries.com/
I can FINALLY announce the news! I have been awarded a British Academy small grant!!
This work will be on safeguarding knowledge about floppy disks! The project will include working with @dpc_chat @JennyMitcham @anj on gathering floppy disk information in one place. But will also include interviewing floppy disk experts across communities and cleaning floppy disks with different techniques with the conservation department at the Cambridge University Library!!
Finished the #FSWA training by @stevenseeley and found something cooler than calc.exe to pop: The almost 30 years old dialer.exe. And yes, it's on PATH
In March 2019, I broke a story about how Facebook had been storing unencrypted password data for hundreds of millions of Facebook users.
Today, the lead European Union privacy regulator fined Meta ~$100 million for that security/privacy failure, which Facebook said could have allowed any one of its 200,000 employees to see the plaintext passwords for up to 600M accounts.
