According to The Hacker News, TeamViewer has fixed a security flaw that allows the machine being controlled—referred to as the host—to attack the computer that connects and takes control—the viewer—during a remote session. In standard TeamViewer usage, the viewer initiates the connection and assumes control of the host.
If the host is maliciously accessed or compromised, it can exploit this flaw to cause the viewer’s TeamViewer application to crash. Depending on the operating system platform involved, the host may also be able to execute additional code after the crash occurs.
The issue relates specifically to interactions within remote control sessions where one machine (the host) is controlled by another (the viewer). TeamViewer addressed the vulnerability following internal review and remediation efforts. No details were provided regarding when the fix was deployed, the scope of affected versions, or user impact beyond the described crash behavior.
