An integer overflow in the remote-control screen processing component of TeamViewer clients (Full Client, Portable and Remote Control App) prior to version 15.83 may allow a malicious remote host to cause a denial of service or, depending on the platform, potentially execute arbitrary code with the privileges of the viewer process.
