So you want to use your professional @ulb.be email address in a non-Outlook application? Silly you, as if it would be straightforward and a well thought out entreprise-wide migration.
Install the ExQuilla extension, then add your account through its dedicated menu in the options. By the end of the 30-days trial, you should receive a banner notification in Thunderbird to purchase a licence (10€/year).

Building the basic stack overflow, we can exploit the same vulnerability to spawn a shell.
This time, we won't be using gets but strcpy that copies a string into a buffer.
#include <stdlib.h>
#include
By abusing the leniency of some C functions when it comes to filling buffers with user-provided information, we can reach other restricted parts of the program, or even execute arbitrary code.
In this demonstration, we will see how a buffer is filled in the stack using the gets function and how overflowing it will allow us the execute a function that should never be called otherwise in the program.
All the addresses used in the snippets and explanations are specific to the setup used to build this write-up. You will need to adapt them to your use-case in order to replicate the behaviour of this exploit.
Some useful GDB commands for the exercise:
Hello,
To access the BEAMS computing server, you need to connect to two VPNs:
ULB's (if your not on premise): https://monulb.ulb.be/fr/web/support/-/comment-utiliser-ulb-vpn- (you can translate the page in English at the bottom)
BEAMS's through openVPN (If you're not connected to a BEAMS network through WiFi of Ethernet). If you don't have one yet, you can ask Axel Dero (axel.dero@ulb.ac.be) to create you a certificate.
You can then connect through SSH to the IP 192.168.0.60. Your username is xx and you password xx
DependencyInstaller.sh should be run before anything else.
Problem is, it only recognizes Ubuntu and CentOS. The content can be applied in a Debiane environment almost seamlessly, though. On the BEAMS server, the following needed to be installed: libboost1.74-dev libeigen3-dev libspdlog-dev swiglemon is not suitable in the official repo, so it needs to be installed manually:
wget http://lemon.cs.elte.hu/pub/sources/lemon-1.3.1.tar.gz
tar -xf lemon-1.3.1.tar.gz
cd lemon-1.3.1cmake -B build .
In a directory with git VCS:
latexdiff-vc --git --flatten -r <rev-hash> full.tex
where full.tex is the root tex file, including (or inputting) several subfiles or not.
You can then compile the resulting .tex file:
pdflatex -shell-escape full-diff.tex
Note that the --pdf option is supposed to do it in one go, but the need for -shell-escape in my case makes the process fail.
If you simply want to generate a diff file with the previous commit in your tree,
À répéter cinq fois : lancer 3d6 et choisir (1) de garder le résultat de côté ou (2) relancer les dés. On peut relancer une seule fois les dés, le nouveau résultat écrasant le précédent, même s'il est pire.
Une fois les cinq résultats obtenus, on les attribue à chaque caractéristique.
