Old Apache Code At Root of Android FakeID Mess
by Peter Reutemann 30 Jul '14

30 Jul '14

'A four-year-old vulnerability in an open source component that is a critical part of Android leaves hundreds of millions of mobile devices susceptible to silent malware infections. The vulnerability affects devices running Android versions 2.1 to 4.4 ("KitKat"), according to a statement released by Bluebox. The vulnerability was found in a package installer in affected versions of Android. The installer doesn't attempt to determine the authenticity of certificate chains that are used to vouch for new digital identity certificates. In short, Bluebox writes, "an identity can claim to be issued by another identity, and the Android cryptographic code will not verify the claim." The security implications of this are vast. Malicious actors could create a malicious mobile application with a digital identity certificate that claims to be issued by Adobe Systems. Once installed, vulnerable versions of Android will treat the application as if it was actually signed by Adobe and give it access to local resources, like the special webview plugin privilege, that can be used to sidestep security controls and virtual 'sandbox' environments that keep malicious programs from accessing sensitive data and other applications running on the Android device. The flaw appears to have been introduced to Android through an open source component, Apache Harmony. Google turned to Harmony as an alternative means of supporting Java in the absence of a deal with Oracle to license Java directly. Work on Harmony was discontinued in November, 2011. However, Google has continued using native Android libraries that are based on Harmony code. The vulnerability concerning certificate validation in the package installer module persisted even as the two codebases diverged.' -- source: http://news.slashdot.org/story/14/07/29/2230242 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

The great Ars experiment—free and open source software on a smartphone?!
by Peter Reutemann 29 Jul '14

29 Jul '14

"Android is a Google product—it's designed and built from the ground up to integrate with Google services and be a cloud-powered OS. A lot of Android is open source, though, and there's nothing that says you have to use it the way that Google would prefer. With some work, it’s possible to turn a modern Android smartphone into a Google-less, completely open device—so we wanted to try just that. After dusting off the Nexus 4 and grabbing a copy of the open source parts of Android, we jumped off the grid and dumped all the proprietary Google and cloud-based services you'd normally use on Android. Instead, this experiment runs entirely on open source alternatives. FOSS or bust!" -- source: http://bit.ly/1ppiC8V First time that I came across F-Droid, the FLOSS app catalogue: https://f-droid.org/ Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

seL4 Verified Microkernel Now Open Source
by Peter Reutemann 29 Jul '14

29 Jul '14

'Back in 2009, OKLabs/NICTA announced the first formally verified microkernel, seL4 (a member of the L4 family). Alas, it was proprietary software. Today, that's no longer the case: seL4 has been released under the GPLv2 (only, no "or later versions clause" unfortunately). An anonymous reader writes OSnews is reporting that the formally verified sel4 microkernel is now open source: "General Dynamics C4 Systems and NICTA are pleased to announce the open sourcing of seL4, the world's first operating-system kernel with an end-to-end proof of implementation correctness and security enforcement. It is still the world's most highly assured OS." Source is over at Github. It supports ARM and x86 (including the popular Beaglebone ARM board). If you have an x86 with the VT-x and Extended Page Table extensions you can even run Linux atop seL4 (and the seL4 website is served by Linux on seL4).' -- source: http://developers.slashdot.org/story/14/07/29/1913259 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"
by Peter Reutemann 27 Jul '14

27 Jul '14

'A pointed critique from Linus Torvalds of GCC 4.9.0. after a random panic was discovered in a load balance function in Linux 3.16-rc6. in an email to the Linux kernel mailing list outlining two separate but possibly related bugs, Linus describes the compiler as "terminally broken," and worse ("pure and utter sh*t," only with no asterisk). A slice: "Lookie here, your compiler does some absolutely insane things with the spilling, including spilling a *constant*. For chrissake, that compiler shouldn't have been allowed to graduate from kindergarten. We're talking "sloth that was dropped on the head as a baby" level retardation levels here .... Anyway, this is not a kernel bug. This is your compiler creating completely broken code. We may need to add a warning to make sure nobody compiles with gcc-4.9.0, and the Debian people should probably downgrate their shiny new compiler."' -- source: http://linux.slashdot.org/story/14/07/27/1838219 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Raspberry Pi Gameboy
by Peter Reutemann 23 Jul '14

23 Jul '14

'An enterprising hacker took on a project to rebuild a broken Gameboy using emulation software, a Raspberry Pi, and a few other easily-obtainable parts. The result: success! The hacker has posted a detailed walkthrough explaining all of the challenges and how they were solved. "Using a Dremel, I cut out a most of the battery compartment as well as some posts that on the case for the LCD that would no longer be needed. Doing so, the Pi sits flush with the back of the DMG case. ... The screen was the first challenge. The screen runs off 12V out of the box which wouldn't work with the USB battery pack. The USB battery pack is rated at 5V, 1000mAH so the goal was go modify the screen to allow it to run at 5V. ... I finally got it to work by removing the power converter chip as well as soldering a jumper between the + power in and the resister on the top right."' -- source: http://build.slashdot.org/story/14/07/23/2138217 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Exodus Intelligence Details Zero-Day Vulnerabilities In Tails OS
by Peter Reutemann 22 Jul '14

22 Jul '14

"Tails OS, the Tor-reliant privacy-focused operating system made famous by Edward Snowden, contains a number of zero-day vulnerabilities that could be used to take control of the OS and execute code remotely. At least that's according to zero-day exploit seller Exodus Intelligence, which counts DARPA amongst its customer base. The company plans to tell the Tails team about the issues "in due time", said Aaron Portnoy, co-founder and vice president of Exodus, but it isn't giving any information on a disclosure timeline. This means users of Tails are in danger of being de-anonymised. Even version 1.1, which hit public release today (22 July 2014), is affected. Snowden famously used Tails to manage the NSA files. The OS can be held on a USB stick and leaves no trace once removed from the drive. It uses the Tor network to avoid identification of the user, but such protections may be undone by the zero-day exploits Exodus holds." -- source: http://tech.slashdot.org/story/14/07/22/165231 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

The "Rickmote Controller" Can Hijack Any Google Chromecast
by Peter Reutemann 21 Jul '14

21 Jul '14

'Dan Petro, a security analyst for the Bishop Fox IT consulting firm, built a proof of concept device that's able to hack into any Google Chromecasts nearby to project Rick Astley's "Never Gonna Give You Up," or any other video a prankster might choose. The "Rickmote," which is built on top of the $35 Raspberry Pi single board computer, finds a local Chromecast device, boots it off the network, and then takes over the screen with multimedia of one's choosing. But it gets worse for the victims: If the hacker leaves the range of the device, there's no way to regain control of the Chromecast. Unfortunately for Google, this is a rather serious issue with the Chromecast device that's not too easy to fix, as the configuration process is an essential part of the Chromecast experience.' -- source: http://tech.slashdot.org/story/14/07/21/1956258 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

meeting next Monday

21 Jul '14

Hi there We have a meeting coming up next Monday: "The Yubikey is one time password generator that conveniently connects a USB keyboard to your PC. It is port powered and small enough to kept on your keyring. The Yubikey uses Yubico's authentication server and can be used conveniently with Lastpass.com to provide two factor authentication to your online password vault. Third parties have written yubikey authentication mechanisms to secure restricted access to Apache webservers. There are many other applications and there are alternative hardware yubikeys capable of connection to smart phones. The authentication server technology is open source allowing users to create their own authentication servers. Yubico provides their service for free. At roughly $US25 a key, the technology is very competitively priced (cf RSA tokens) and well within the price range of most enthusiasts. Unfortunately, Google doesn't (yet) provide it as an option for their two factor authentication. The presenter will talk about lastpass.com and apache authentication." http://www.meetup.com/WaikatoLinuxUsersGroup/events/185499622/ Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

MicroxWin Creates Linux Distribution That Runs Debian/Ubuntu & Android Apps
by Peter Reutemann 21 Jul '14

21 Jul '14

"VolksPC who developed MicroXwin as a lightweight X Window Server has come up with their own Linux distribution. Setting apart VolksPC's distribution from others is that it's based on both Debian and Android and has the capability to run Debian/Ubuntu/Android apps together in a native ARM experience. The implementation doesn't depend on VNC or other similar solutions of the past that have tried to join desktop apps with mobile Android apps. This distribution is also reportedly compatible with all Android applications. The distribution is expected to begin shipping on an ARM mini-PC stick." -- source: http://news.slashdot.org/story/14/07/20/1218256 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Linux Needs Resource Management For Complex Workloads
by Peter Reutemann 21 Jul '14

21 Jul '14

'Resource management and allocation for complex workloads has been a need for some time in open systems, but no one has ever followed through on making open systems look and behave like an IBM mainframe, writes Henry Newman at Enterprise Storage Forum. Throwing more hardware at the problem is a costly solution that won't work forever, he notes. Newman writes: "With next-generation technology like non-volatile memories and PCIe SSDs, there are going to be more resources in addition to the CPU that need to be scheduled to make sure everything fits in memory and does not overflow. I think the time has come for Linux – and likely other operating systems – to develop a more robust framework that can address the needs of future hardware and meet the requirements for scheduling resources. This framework is not going to be easy to develop, but it is needed by everything from databases and MapReduce to simple web queries."' -- source: http://linux.slashdot.org/story/14/07/20/0317216 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

LibreSSL PRNG Vulnerability Patched
by Peter Reutemann 16 Jul '14

16 Jul '14

'The OpenBSD project late last night rushed out a patch for a vulnerability in the LibreSSL pseudo random number generator (PRNG). The flaw was disclosed two days ago by the founder of secure backup company Opsmate, Andrew Ayer, who said the vulnerability was a "catastrophic failure of the PRNG." OpenBSD founder Theo de Raadt and developer Bob Beck, however, countered saying that the issue is "overblown" because Ayer's test program is unrealistic. Ayer's test program, when linked to LibreSSL and made two different calls to the PRNG, returned the exact same data both times. "It is actually only a problem with the author's contrived test program," Beck said. "While it's a real issue, it's actually a fairly minor one, because real applications don't work the way the author describes, both because the PID (process identification number) issue would be very difficult to have become a real issue in real software, and nobody writes real software with OpenSSL the way the author has set this test up in the article."' -- source: http://linux.slashdot.org/story/14/07/16/1950235 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
