Here’s a video article by Laura Chappell on how you can make your wireless snooping a bit more comfy by adding columns for your wireless antenna signal strength.

Microsoft announced last December 15 of yet another major flaw in version 7 of its Internet Explorer browser which allows remote code execution on the target computer (as if the others do not already).

Dubbed as Microsoft Security Advisory (961051), the advisory went on to discuss the issue as follows:

The vulnerability exists as an invalid pointer reference in the data binding function of Internet Explorer. When data binding is enabled (which is the default state), it is possible under certain conditions for an object to be released without updating the array length, leaving the potential to access the deleted object’s memory space. This can cause Internet Explorer to exit unexpectedly, in a state that is exploitable.

It appears also that its not only IE7 that’s affected. It affects versions up to IE8 also. Even the BBC has snatched this issue as well.

What was weird for me was that the Full Disclosure community did not make any reaction to this disclosure by Microsoft. Or it might be too early as the secinfo experts and enthusiasts are scrambling to verify this if at all.

My take on this is - what’s new? Honestly, I’m not surprised at all.

I was doing my daily round of sifting through opensource newsbits when I came across Adeona. According to its creators, it can be described as:

Adeona is the first Open Source system for tracking the location of your lost or stolen laptop that does not rely on a proprietary, central service. This means that you can install Adeona on your laptop and go — there’s no need to rely on a single third party. What’s more, Adeona addresses a critical privacy goal different from existing commercial offerings. It is privacy-preserving. This means that no one besides the owner (or an agent of the owner’s choosing) can use Adeona to track a laptop. Unlike other systems, users of Adeona can rest assured that no one can abuse the system in order to track where they use their laptop.

Adeona is designed to use the Open Source OpenDHT distributed storage service to store location updates sent by a small software client installed on an owner’s laptop. The client continually monitors the current location of the laptop, gathering information (such as IP addresses and local network topology) that can be used to identify its current location. The client then uses strong cryptographic mechanisms to not only encrypt the location data, but also ensure that the ciphertexts stored within OpenDHT are anonymous and unlinkable. At the same time, it is easy for an owner to retrieve location information.

Adeona has builds for Linux, Mac OS X, and Windows ready for download and follow the installation steps should anyone wanna try it out.

Though I currently do not own a laptop or a UMPC (planning to), but this sure is a nice must-have for anybody that does have one or several. I gotta see this for myself.

Although Intrepid Ibex is not yet geared for release, I’ve decided to make my own wallpaper for it.

It’s not much but a work in progress. Everything’s done in XaraLX on Xubuntu Hardy. And yes, I have already submitted this to Artwork/Incoming/Intrepid under Dark Ibex Wallpaper.

Enjoy!

In anticipation of Software Freedom Day this coming September 20, I’ve decided to commemorate it by creating my own Software Freedom Day 2008 button. You can find the button at the right panel in this blog.

If you want to join us in celebrating Software Freedom Day, you can create your own graphic button or use my graphic in your website or blog. Do feel free to give credit where there is due.

You can pick up or link the graphic here.

Happy Software Freedome Day!

I would like to thank Peng Hardin for mentioning my wee little report on Chrome’s behaviour on Wine 1.1.3. My little post has this tiny speck of a link on Ubuntu Weblogs.

Thanks also to Roy Shea and Dan Kegel over at WineHQ. As expected, them and a couple of other guys at WineHQ have rolled out Wine 1.1.4 with fixes for Google Chrome and I’m glad I was able to contribute to Wine’s improvement in little ways that I can.

Good luck to all of us and let’s have that Wine please!

With Google doing a public beta test of Google Chrome I’ve taken a few steps further to see what it can do. However, sadly for me, GC is currently on a Windows-only build so no dice for native Linux version. So I had to resort to “drastic” measures - try to see if it runs on Wine.

So I got the offline installer here and installed on top of Wine. The installation went ok, with Wine adding a desktop shortcut and menu entries. I tried to run GC and bam, a browser with rounder corners and blue header pops up. So far so good.

Then I noticed that the address bar is all black. Though I can type a URL, it doesn’t open the site I wan’t to visit. Tried it a couple of times, still no dice. Looking at the log I prepped, seems there are some components not working properly. So I ended up firing a report to WineHQ and see what can be done.

Nope, I currently don’t have the time to find the bug for GC on Wine. I’m making the Google Chrome team do that. At least with the WineHQ notified, I can expect to have a working GC on Wine.

Or not.

UPDATE:

Google Chrome now works on Wine 1.1.3. However, additional parameters must be added when you invoke wine on the command line. And sorry, HTTPS access is not yet available/foolproof.

Just fire up Wine in the terminal like so:

env WINEPREFIX=”/home/anakin/.wine” wine “C:\windows\profiles\anakin\Local Settings\Application Data\Google\Chrome\Application\chrome.exe” –new-http –in-process-plugins

You have to also make sure that you have Riched20 and Riched30 installed using Winetricks (thanks Roy Shea at WineHQ!).

This method was further confirmed at UbuntuForums, and also confirmed by “nelson”. A good how-to is also available recently at HowToDude.

UPDATE 2:

Filed another bug report with WineHQ regarding HTTPS access on Google Chrome on Wine 1.1.3.
