Use the -u flag instead of -a. Doesn't add new files, just existing ones.

Oops, you're right. I was thinking of those as nearly interchangeable but they're actually pretty different. I might give it a try when I have a chance, I'll let you know if anything comes of it.

I wonder if an adversarial user could bypass the checks and achieve memory corruption / code execution. Maybe not a practical attack in most situations but a fun exercise. > This includes things like asm volatile("" : : :

Yes but at best their "solution" is equally secure, not any better.

That's a privacy violation, not relevant.

For the old version support. Why not do some compile time #ifdef SUPPORT_ES3? That way library writers can support it and if the user doesn't need it they can disable it at compile time and all the legacy code will be removed

It doesn't bypass it exactly, it's still accessing it via virtual memory and the page tables. It's just that the kernel maintains one big linear memory map of RAM that's writable.

Citation needed. We don't even know if indistinguishability obfuscation is possible.

Amusing because gmail doesn't even follow spec. I had to workaround gmail quirks when I worked at an email company. Better than outlook though. What a nightmare.

Half the time when people say they're using telnet (including in this thread) they're really just using the client as a TCP client, not doing anything with the Telnet protocol. No one is stopping you from using the telnet client.

That doesn't work on any* NAND flash device, be it a flash drive, NVME, SATA, whatever. The block device you see is an abstraction provided by the SSD controller. In reality, the flash capacity is larger. Pages are swapped out for wear

To maximize device performance when wiping a drive to use for something else, I use nvme format with --ses=1. Which in theory should free all of the blocks on the flash. Really hard to find good documentation on this stuff. Doesn't hel

As far as I know, there is NO way to securely erase a USB flash drive (barring some undocumented vendor specific commands that may exist).

They explicitly check if the referrer is hackernews and do that.

Switch to an ILP32 ABI and you get a lot of that space back

I don't know if it was filename exactly, but a similar story: > Jon Ross, who wrote the original version of SimCity for Windows 3.x, told me that he accidentally left a bug in SimCity where he read memory that he had just freed. Yep

What's preventing a compromised kernel on one core from hijacking the other cores? This doesn't seem like much of a security boundary
23.
by IAmLiterallyAB 1y ago
My limited understanding is. There is no safe subset (That's what was just discontinued, profiles are the alternative.) And C++ code simply doesn't have the necessary info to make safety decisions. Sean explains it better than I c
