Yahoo Webcam Security Problem

Yahoo Webcam Security Problem Do you use Yahoo Messenger? Have a webcam that you switch on for others to see you? Then you’d better be careful for a while. Chinese researchersreported that they’d found a zero day vulnerability in the service’s webcam, which McAfee reproduced yesterday. It affects users on MessengerV8.1.0.413. According to McAfee, the vulnerability can be triggered when a user accepts a webcam invitation. This can leave the user open to remote-code execution attacks. However, the companysaid it had yet to see any exploitation code published for the vulnerability. McAfee has informed Yahoo of the problem. “Since learning of this issue, we have been actively workingtowards a resolution and expect to have a fix shortly,” a Yahoo spokesman informed InformationWeek in an e-mail. “Yahoo takes securityseriously and consistently employs measures to help protect our users.” This follows on from a report by eEye Digital Security which found multiple flaws in Version 8 of Yahoo Messengerwhich could allow a remote hacker to take control of a user’s system. Yahoo also experienced a problem in June, a buffer-overflow flaw in an Active X control, which was patched. For now, Yahoo is advising Messenger users not to accept webcam invitations from untrusted sources until a patch has been released and installed on the computer, and to block outgoing traffic on TCPport 5100.

The Windows 11 24H2 update is causing even more problems

The Windows 11 24H2 update had already been giving users a real headache with problems such as bugs for visual layouts and flaws for certain wallpaper apps. And now, as Microsoft confirms in a support document, some people without administrative privileges can't change the time zone in the Date & Time view, among myriad other issues related to the important Windows 11 update.

A Feedback Hub post also reports a time issue after exiting Sleep Mode, specifically after about one out of every five overnight sleep cycles. There is also a report that the time is not syncing correctly following daylight saving time. Put differently, the update doesn't break the time zone, but only affects the toggle or makes it very difficult to modify it.

Microsoft calls Recall one of ‘the most secure experiences’ it’s ever built

As part of its Ignite 2024 announcements, Microsoft has provided an update on how its AI-powered Recall feature will work in the context of an IT department. Noting that the company has "heard your feedback," specifically in terms of it needing it to be more "secure and controllable," Microsoft claims to have gotten its ducks in a row for the launch of its controversial new Windows 11 feature.

Microsoft says that Recall "will ship with meaningful security enhancements, including additional layers of data encryption and Windows Hello protection, making it one of the most secure experiences we have ever built." Whether or not this will be enough to satisfy the security community, however, is still to be determined.

Nvidia’s new GPUs are already running into problems

Nvidia's latest Blackwell GPUs are running into problems in the data center, reports The Information. According to the report, Nvidia's customers are worried about how well the AI accelerators will hold up, as overheating issues have caused delays in server racks being deployed for AI training.

The Blackwell architecture is at the heart of both Nvidia's next-gen AI accelerators and its upcoming RTX 50-series graphics cards. In the data center, the architecture was previously delayed due to "design flaws," pushing the deployment of the B100 and B200 GPUs back. That's despite big orders with AI players like Meta, Microsoft, and Google.
