Today we released Plasma 5.2 and this new release comes with two fixes for security vulnerabilities in our screen locker implementation. As I found, exploited, reported and fixed these vulnerabilities I decided to put them a little bit into context.
The first vulnerability concerns our QtQuick user interface for the lock screen. Through the Look and Feel package it was possible to send the login information to a remote location. That’s pretty bad but luckily also only a theoretical problem: we have not yet implemented a way to install new Look and Feel packages from the Internet. So we found the issue before any harm was done.
There is no shortage of security-focused Linux distributions on the market, and among them is Pentoo Linux. While some security-focused Linux distributions concentrate on privacy, like Tails, others like Kali Linux and Pentoo focus on security research, providing tools that enable research and penetration testing. Pentoo Linux differentiates itself from other security Linux distributions in a number of ways. The primary difference is the fact that Pentoo is based on Gentoo Linux, which is a source-based Linux distribution that uses the Portage package-management system. Gentoo has capabilities known as "Hardened Gentoo," which Pentoo also inherits, providing users with additional security configuration and control for the Linux distribution itself. Pentoo 2015 RC 3.7 was released Jan. 5, providing updated tools and features. Among the new features is the integrated ability to verify that the distribution files have not been corrupted. Pentoo provides many applications for security analysis, including wireless, database, exploit, cracking and forensic tools. In this slide show, eWEEK looks at key features and tools in the Pentoo 2015 RC3.7 release.
Open source software vendors do something akin to selling air: They get people to pay for something that easily, and perfectly legally, can be had for free. But added security is becoming an increasingly important part of the value proposition, as Red Hat (RHT), maker of one of the leading Linux enterprise distributions, emphasized this week in a statement on its software subscriptions.
Tor is apparently no longer a safe place to run a marketplace for illegal goods and services. With the alleged operator of the original Silk Road marketplace, Ross Ulbricht, now going to trial, the arrest of his alleged successor and a number of others in a joint US-European law enforcement operation, and the seizure of dozens of servers that hosted "hidden services" on the anonymizing network, the operators of the latest iteration of Silk Road have packed their tents and moved to a new territory: the previously low-profile I2P anonymizing network.
Red Hat achieved its latest successful FIPS 140 validation back in April 2013. Since then, a lot has happened. There have been well publicized attacks on cryptographic protocols, weaknesses in implementations, and changing government requirements. With all of these issues in play, we want to explain what we are doing about it.
