So the Department of Energy emailed me

The folks from Xiaomi didn't pick up their Pwnie for Lamest Vendor Response, so we're keeping it safe for them until they decide to come accept it.

Taylorism is a management philosophy based on using scientific optimization to maximize labor productivity and economic efficiency.

Here's the result of making the false Taylorist assumption that the output of scientific research is scientific papers—the more, faster, and cheaper, the better.

Me to Microsoft: You can avoid a whole class of vulnerability if non-admin users can't create subdirectories off of the root directory. You should fix this.

MS: Nah.

Me: Well, you folks should probably at least run Crassus on your code.

MS: Nah.

In our writeup https://sector7.computest.nl/post/2024-06-cve-2024-20693-windows-cached-code-signature-manipulation/ about CVE-2024-20693, we noted that Microsoft did not structurally address the trust of "$KERNEL.*" Extended Attributes on SMB shares. Today's Patch Tuesday addresses #CVE-2024-38133, doing the same thing again, but in this case even an USB disk would work!

I think this may be the first time we got an "Exploitation More Likely", so achievement unlocked I guess?

‼️Big day! NIST publishes standards for next-generation cryptography (cipher, digital signature) understood as resistant to attacks with future quantum computers. Migration will not be a piece of cake, but there’s time. https://nvlpubs.nist.gov/nistpubs/fips/nist.fips.203.pdf https://nvlpubs.nist.gov/nistpubs/fips/nist.fips.204.pdf https://nvlpubs.nist.gov/nistpubs/fips/nist.fips.204.pdf

Seeking help from an IT security person - please share!

I run an open source, federated event sharing site, #Gathio (https://gath.io). A few days ago, it was victim to a ransomware attack that deleted the database. I need a few hours of someone's time (paid of course!) to sit with me and go through my security configuration ASAP.

Sometimes, running open source, free, community services _sucks_.

fun Linux fact:

There are at least two places in the Linux kernel where performance-sensitive code paths use a, uh, retrospective approach to memory safety, where you do the memory read first (and suppress the occasional kernel page fault) and worry about making sure it was memory-safe later.

One of the two is in the SLUB allocator's lockless allocation fastpath: https://elixir.bootlin.com/linux/v6.10.4/source/mm/slub.c#L544
It (1) first loads the pointer to the current top freelist element, then (2) reads the next freelist pointer out of that element, and (3) does a double-wide atomic compare-exchange to check if it raced and replace the freelist head. The read in step (2) can return garbage or fault if someone else concurrently modified the freelist (basically it can be UAF), but in that case step (3) that uses the result of the read is guaranteed to fail, so it's fine.

The other one is in the Virtual File System layer, used for printing pathnames (like for getcwd()):
https://elixir.bootlin.com/linux/v6.10.4/source/fs/d_path.c#L50
As the comment there explains:

 * The source of the prepend data can be an optimistic load
 * of a dentry name and length. And because we don't hold any
 * locks, the length and the pointer to the name may not be
 * in sync if a concurrent rename happens, and the kernel
 * copy might fault as a result.
 *
 * The end result will correct itself when we check the
 * rename sequence count, but we need to be able to handle
 * the fault gracefully.

So this one can race so that OOB memory is copied into the path buffer, but the kernel will afterwards notice that the "how many rename operations have happened" counter has gone up (or that the "we are currently in the middle of a rename" bit is set), discard the result, and try again.

Resorts World (one of the hotels defcon contracted with to offer rooms to con attendees) decided to pull some clown shit and announce they’re doing daily room checks for “hacking” as some knee-jerk response to the MGM ransom attack last year. Someone leaked the checklist they gave to employees and it’s even dumber than you thought.
