Parrot Security OS 4.7 Released With New Linux Kernel, Menu Structure, Tools Improvements And Many Changes

In Sep 18 2019, Parrot Security OS 4.7 has released, with many new following changes below.

Latest Linux 5.2.x series
The new ISO files of Parrot 4.7 are being released only now, but we were the first Debian derivative distribution to introduce Linux 5.1 and 5.2 to all our users, and now ParrotSec team is ready to offer it also with our ISO files rebild cycle to support more devices and integrate all the latest linux features from the beginning.

New sandbox behavior (opt-in rather than opt-out)
Sandboxing is a great thing, and ParrotSec team was in the first line when they introduced our custom Firejail and AppArmor solution for the first time many years ago. We still want to improve such feature and ParrotSec team has a whole team dedicated to improve sandboxing and hardening of the Parrot Security OS system, but ParrotSec team had to face the many users with issues caused by the restrictions of our sandbox.

In Parrot Security OS 4.7 the sandbox is disabled by default, and users can decide wether to start an application sandboxed or not. You can easily start the sandboxed version of an installed program from the /sandbox/ folder or from a dedicated menu that ParrotSec team plans to improve in the future (meanwhile the search feature of the bottom menu will fit all your needs), or you can re-enable it by default by using the firecfg tool.

New menu structure and tools improvements
The pentesting menu structure was refactored and re-designed to make tools easier to access in a more logical hierarchical structure. New tools were also added to the project, and ParrotSec team plans to add even more in the future. Not all of them are going to be pre-installed, but a good set of tools in our repository enables pentesters to build up the perfect pentest system for their specific needs, regardless the default package selection picked by ParrotSec team.

Domain changes
To reflect the neutrality of a distro that started as a pentest-only system and became more general purpose later with Parro Home, the community voted through a democratic process to switch to parrotlinux.org as the new default domain of the project.

ParrotSec team will still use ParrotSec.org for other things (included the old email addresses), and they introduced other project domains to handle specific parts of the infrastructure.

Repository changes
ParrotSec team is preparing to integrate a future LTS branch, so they decided to rename the current repository from stable to rolling. Nothing changes for the end user, and the current Parrot Security OS branch will continue to behave the same as before, but now with a different name to better reflect the rolling release nature of the system, waiting for the LTS edition to join the Parrot Security OS family along side the rolling branch in a similar way OpenSUSE does.

New MATE 1.22 release: Parrot Security OS 4.7 ships with the latest MATE 1.22 desktop environment.

Miscellaneous: New Firefox Browser 69, the latest Radare2 and cutter versions and many other important upgrades are all aboard as expected in a properly developed rolling release distro.

How to upgrade to the lastest Parrot Security OS version
You can update your existing Parrot Security OS system with this command:
sudo parrot-upgrade

Or use the raw apt command

sudo apt update
sudo apt full-upgrade

Don't forget to use this command regularly (at least once a week) to receive the latest security updates and bugfixes from the Parrot Security OS repository.

Or you can download the latest release from official download page.

TLS V1.2 Sigalgs Remote Crash (CVE-2015-0291)

OpenSSL 1.0.2a fix several security issues, one of them let crash TLSv1.2 based services remotelly from internet.

Regarding to the TLSv1.2 RFC, this version of TLS provides a "signature_algorithms" extension for the client_hello.

Data Structures

If a bad signature is sent after the renegotiation, the structure will be corrupted, becouse structure pointer:
s->c->shared_sigalgs will be NULL, and the number of algorithms:
s->c->shared_sigalgslen will not be zeroed.
Which will be interpreted as one algorithm to process, but the pointer points to 0x00 address.

Then tls1_process_sigalgs() will try to process one signature algorithm (becouse of shared_sigalgslen=1) then sigptr will be pointer to c->shared_sigalgs (NULL) and then will try to derreference sigptr->rhash.

This mean a Segmentation Fault in tls1_process_sigalgs() function, and called by tls1_set_server_sigalgs() with is called from ssl3_client_hello() as the stack trace shows.

StackTrace

The following code, points sigptr to null and try to read sigptr->rsign, which is assembled as movzbl eax, byte ptr [0x0+R12] note in register window that R12 is 0x00

Debugger in the crash point.

radare2 static decompiled

The patch fix the vulnerability zeroing the sigalgslen.

BurpSuite Introduction & Installation

What is BurpSuite?
Burp Suite is a Java based Web Penetration Testing framework. It has become an industry standard suite of tools used by information security professionals. Burp Suite helps you identify vulnerabilities and verify attack vectors that are affecting web applications. Because of its popularity and breadth as well as depth of features, we have created this useful page as a collection of Burp Suite knowledge and information.

In its simplest form, Burp Suite can be classified as an Interception Proxy. While browsing their target application, a penetration tester can configure their internet browser to route traffic through the Burp Suite proxy server. Burp Suite then acts as a (sort of) Man In The Middle by capturing and analyzing each request to and from the target web application so that they can be analyzed.

Everyone has their favorite security tools, but when it comes to mobile and web applications I've always found myself looking BurpSuite . It always seems to have everything I need and for folks just getting started with web application testing it can be a challenge putting all of the pieces together. I'm just going to go through the installation to paint a good picture of how to get it up quickly.

BurpSuite is freely available with everything you need to get started and when you're ready to cut the leash, the professional version has some handy tools that can make the whole process a little bit easier. I'll also go through how to install FoxyProxy which makes it much easier to change your proxy setup, but we'll get into that a little later.

Requirements and assumptions:

Mozilla Firefox 3.1 or Later Knowledge of Firefox Add-ons and installation The Java Runtime Environment installed

Download BurpSuite from http://portswigger.net/burp/download.htmland make a note of where you save it.

on for Firefox from https://addons.mozilla.org/en-US/firefox/addon/foxyproxy-standard/

If this is your first time running the JAR file, it may take a minute or two to load, so be patient and wait.

Video for setup and installation.

You need to install compatible version of java , So that you can run BurpSuite.
