QUESTION

Segmentation fault when decrypting with openssl in C

Asked 2021-Jun-06 at 05:48

I'm trying to decrypt a message encrypted with AES 192 ECB and getting a segmentation fault and don't know where to look anymore. I know ECB is unsafe, but it is not for a production application.

I already checked my readFile method, it works (I wrote the ciphre back into a file and checked with the diff tool)
The key is 24 Bytes long (checked with ls and hexdump)
ECB has no IV-Vector as far as I know, so I have set it to NULL
for the decryption part I used the example at https://wiki.openssl.org/index.php/EVP_Symmetric_Encryption_and_Decryption to get started
I think the problem is at EVP_DecryptUpdate
I tried to track it down further with gdb but I have no experience with this and only got

0x00007ffff798089d in ?? () from /usr/lib64/libcrypto.so.1.1

Thank you for your time.

Ok, so I didnt completely resolved it, but I found a work around, also i've forgot to mention something important here I was actually compiling from a VM, through a VM shared folder (VMware Fusion) while coding on my host computer.

anyways, instead of using the share, i copied the file using scp and then i had no encoding problems... not completely resolved issue, but for now I can live with that.

Which format does /dev/urandom output?

Asked 2021-May-24 at 01:22

Hi can somebody tell me which format /dev/urandom outputs and How i can replicate the output manually?.

I am trying to remove the idea of randomness from the script i am writing/using and instead place an incrementing value in order like 1,2,3,4,5 etc...

Yet /dev/urandom does not output integers, i do not know which format the output is. It looks like some kind of Hex/Binary

I think this is one way of using /dev/urandom

Answered 2021-May-24 at 00:50

There is no format. It's random bytes. Every byte is random.

QUESTION

Why am I not receiving interrupts on Port Status Change Event with the Intel's xHC on QEMU?

Asked 2021-Apr-26 at 06:13

I'm coding a small OS kernel which is supposed to have a driver for the Intel's xHC (extensible host controller). I got to a point where I can actually generate Port Status Change Events by resetting the root hub ports. I'm using QEMU for virtualization.

I ask QEMU to emulate a USB mouse and a USB keyboard which it seems to do because I actually get 2 Port Status Change Events when I reset all root hub ports. I get these events on the Event Ring of interrupter 0.

The problem is I can't find out why I'm not getting interrupts generated on these events.

I'm posting a complete reproducible example here. Bootloader.c is the UEFI app that I launch from the OVMF shell by typing fs0:bootloader.efi. Bootloader.c is compiled with the EDK2 toolset. I work on Linux Ubuntu 20. Sorry for the long code.

The file main.cpp is a complete minimal reproducible example of my kernel. All the OS is compiled and launched with the 3 following scripts:

I finally got it working by inverting the MSI-X table structure found on osdev.org. I decided to completely reinitialize the xHC after leaving the UEFI environment as it could leave it in an unknown state. Here's the xHCI code for anyone wondering the same thing as me:

QUESTION

Compact shellcode to print a 0-terminated string pointed-to by a register, given puts or printf at known absolute addresses?

Asked 2021-Apr-24 at 08:04

Background: I am a beginner trying to understand how to golf assembly, in particular to solve an online challenge.

EDIT: clarification: I want to print the value at the memory address of RDX. So “SUPER SECRET!”

Create some shellcode that can output the value of register RDX in <= 11 bytes. Null bytes are not allowed.

The program is compiled with the c standard library, so I have access to the puts / printf statement. It’s running on x86 amd64.

...

ANSWER

Answered 2021-Apr-24 at 08:04

Since I already spilled the beans and "spoiled" the answer to the online challenge in comments, I might as well write it up. 2 key tricks:

Create 0x7ffff7e3c5a0 (&puts) in a register with lea reg, [reg + disp32], using the known value of RDI which is within the +-2^31 range of a disp32. (Or use RBP as a starting point, but not RSP: that would need a SIB byte in the addressing mode).

This is a generalization of the code-golf trick of lea edi, [rax+1] trick to create small constants from other small constants (especially 0) in 3 bytes, with code that runs less slowly than push imm8 / pop reg.

The disp32 is large enough to not have any zero bytes; you have a couple registers to choose from in case one had been too close.
Copy a 64-bit register in 2 bytes with push reg / pop reg, instead of 3-byte mov rdi, rdx (REX + opcode + modrm). No savings if either push needs a REX prefix (for R8..R15), and actually costs bytes if both are "non-legacy" registers.

WordPress / PhpStorm script corruption

Asked 2021-Apr-21 at 12:32

When I access certain pages on the WP admin panel, it does not load due to corrupt script files.

I have downloaded WordPress and opened it as a project in PhpStorm (2021.1). I am using PHP 7.4.9 (installed via HomeBrew) and the built-in web server.

I have confirmed that the original script files are not corrupt. When the page loads the scripts via load-scripts.php (load-scripts.php?c=1&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils&ver=5.7.1), which returns a bunch of concatenated scripts, the response contains additional bytes in the middle.
