TeamViewer Releases Hotfix for Permission Hook Vulnerability


Göppingen, December 5, 2017TeamViewer®, Within hours of discovering an injectable C++ DLL vulnerability, TeamViewer’s engineering team provided a fix to address the issue. The vulnerability was first described on GitHub and concerned TeamViewer’s set of permissions. In two different scenarios, attackers could either gain control of the victim’s mouse or switch sides to gain control of the system.

However, the potential threat was limited as the exploit required a legitimate connection to be established first before it could have been applied. Attackers could not randomly target any potential TeamViewer installation. In addition, users always have the ability to terminate a TeamViewer session at any time.

TeamViewer strongly encourages users to update their installation to the latest software version.
