Ubisoft Fixes Uplay Security Flaw
Ubisoft has fixed a security flaw with its Uplay browser plug-in that allowed malicious websites to take over your computer.
The security hole was discovered by a programmer at Google and only affected PC users. Ubisoft was quickly on top of the issue, however. “We have made a forced patch to correct the flaw in the browser plug-in for the Uplay PC application that was brought to our attention earlier today," the publisher said today.
"We recommend that all Uplay users update their Uplay PC application without a Web browser open. This will allow the plug-in to update correctly”. The Uplay network comes integrated with many of Ubisoft's newest PC titles. Below is Ubisoft's full statement.
The browser plugin that we used to launch the application through Uplay was able to take command line arguments that developers used to launch their games while they're being made. This weakness could allow the application to specify any executable to run, rather than just a game. This means it was possible to launch another program on the machine.
The issue was brought to our attention early Monday morning and we had a fix into our QC department an hour and a half later. An automatic patch was launched that fixes the browser plugin so that it will only open the Uplay application. Ubisoft takes security issues very seriously, and we will continue to monitor all reports of vulnerabilities within our software and take swift action to resolve such issues.
To update your Uplay client and apply the patch:
-Close any open web browsers (Internet Explorer, Firefox, Chrome, Opera, etc.) If the web browser is open during the patch it will require restarting the browser.
-Launch the Uplay PC client. The Uplay PC client update will start automatically.
An updated version of the Uplay PC installer is also available to download from Uplay.com.
Q: Is the issue a rootkit as was reported by various media outlets?
The issue is not a rootkit. The Uplay application has never included a rootkit. The issue was from a browser plug-in that Uplay PC utilizes which suffered from a coding error that allowed systems usually used by Ubisoft PC game developers to make their games.
Q: Is this issue related to DRM?
No. The browser plugin issue is just for launching the Uplay application.
Q: Can the browser plugin still launch other executables (programs)?
The browser plugin can now only launch the Uplay application.
