Microsoft plans to force a mandatory Windows Live Messenger upgrade later this month to fix a security vulnerability that could lead to remote code execution attacks.
The vulnerability, caused by an extra character in the Microsoft Active Template Library (ATL), affects users of Windows Live Messenger 8.1 and 8.5.
The mandatory upgrade will start in the middle of September and will force users to apply the latest Live Messenter 14.0.8089 if they want to use Microsoft’s instant messaging service.
More information is available in this Microsoft blog post.
