Canonical announced on Friday that Ubuntu forums have been hacked. The company adds that data such as IP address, username, and email address of over two million users have been compromised. BetaNews reports: Keep in mind, this does not mean that the operating system has experienced a vulnerability or weakness. The only thing affected are the online forums that people use to discuss the OS. Still, such a hack is embarrassing as it happened due to Canonical's failure to install a patch.In a blog post, Jane Silber, Chief Executive Officer, Canonical said, "after some initial investigation, we were able to confirm there had been an exposure of data and shut down the Forums as a precautionary measure. Deeper investigation revealed that there was a known SQL injection vulnerability in the Forumrunner add-on in the Forums which had not yet been patched."
