Details of a nine-year-old security vulnerability with the sudo utility found in numerous Unix and Linux based operating systems have been revealed.

The flaw, which affects the likes of Linux Mint and Elementary OS, could be exploited to give users root privileges on a vulnerable system. Sudo versions 1.7.1 to 1.8.30 are at risk if the pwfeedback option is enabled.

Facebook has announced a raft of changes to its Messenger Kids service, giving parents more control and oversight over what their children are able to do.

Parents are now about to see 30 days' worth of chat logs as well as details of the types of conversation they are having with different contacts. Other new features include the ability to see images that have been shared, and also to remotely log their child out of chat sessions using the Parent Dashboard.

If you used Google Takeout to download an archive of your Google Photos content, there's a chance that someone else may have ended up with your videos.

The company has admitted that for a few days in November last year, "some videos in Google Photos were exported to unrelated users' archives". This means that not only could your videos have ended up on a stranger's computer, but also that you may have received random videos belonging to someone else.

Problematic updates for Windows 10 have become pretty common these days, and now it has happened again.

Microsoft released the KB4532695 update last week to address problems with Explorer which were introduced by the November 2019 Update. But this update has itself been found to cause issues, with users complaining of BSoDs, audio problems and more.

It is now a couple of weeks since Microsoft released Windows 10 Insider Build 19551 to the Fast ring, and it seemed like a fairly unexciting build.

But the release actually gave us an interesting glimpse into Microsoft's future plans to give users more control over the operating system. Specifically, it will soon be possible for Windows 10 users to uninstall the likes of Notepad, Paint and WordPad.

Microsoft has changed its mind about the future of the Surface Hub 2. The company had previously planned to release a processor upgrade in the form of the Surface Hub 2X compute cartridge, but this no longer appears to be the case.

A leaked webinar shows that Microsoft's plans to release a processor- and GPU-enhancing upgrade cartridge have been put on hold, with the company now planning to release a "major software update" for Surface Hub and Surface Hub 2

Microsoft has introduced a new feature to its Edge browser that blocks "potentially unwanted apps" from being downloaded.

At the moment, the security feature is available in the beta version of Microsoft Edge, but it will also be making its way to the stable version of Chromium-based Edge later this month. Strangely, Microsoft has chosen not to switch on the feature by default.

Having now embraced the same engine as Chrome, the Chromium-based Edge is now Microsoft's default browser. If you want to keep using Microsoft Edge Legacy and Internet Explorer 11 for some reason, Microsoft has opened up a way to do so -- and to do so safely.

The company has released virtual machine images that include both web browser. Available free of charge, the images are available for a range of virtualization platforms.

Microsoft is no stranger to using bug bounty programs to track down security problems and other issues with its software and services. Now the company has launched an Xbox bug bounty program, offering payouts of up to $20,000 to anyone finding vulnerabilities.

The particular aim of this bounty program is to find issues with the Xbox Live network and services. Microsoft says the amounts it will pay gamers and security researchers who report problems will depend on the severity and impact of the vulnerability, as well as the quality of the submission.

Microsoft may have dropped Windows 7 like a hot stone, but that doesn't mean everyone is. Recognizing the fact that large numbers of people are going to continue using the aged operating system, most antivirus firms are going to continue to offer support.

Support from the likes of AVG, Avira, Kaspersky and Trend Micro for at least two years is great news for those concerned about the security of sticking with Windows 7. Of course, this doesn't mean that the operating system is entirely safe to use now that it has reached end of life, but with the right software installed, hangers-on can secure their systems somewhat.

The latest update to iOS will please anyone with privacy concerns. iOS 13.3.1 gives iPhone owners the chance to toggle the location-tracking U1 Ultra Wideband chip on and off -- something Apple promised a couple of months ago.

There was controversy when security experts discovered that the chip meant iPhones were periodically tracking people's location even when location services were disabled. Now it is possible to ensure that such tracking cannot be carried out.

Microsoft has issued an optional update for Windows 10 versions 1903 and 1909. Among other things, the update fixes Explorer problems introduced by the November 2019 Update.

The same update is available for both version of Windows 10 because, as Microsoft explains, both "1903 and 1909 share a common core operating system and an identical set of system files". While the update, KB4532695, includes a number of fixes, it is the addressing of Explorer issues that will be most welcomed.

The UK government has announced that -- despite being considered a "high-risk vendor" -- Huawei will be permitted to contribute to the 5G network infrastructure in Britain.

The US recently warned that allowing the Chinese firm to be involved in the rollout of 5G would be "madness", but the UK has chosen to ignore this. Huawei will have limits placed on its contributions, meaning that it will only be able to supply "non-core" elements of the network.

Google is in the mood for a cull at the moment. Having announced the end of support for Chrome Apps, the company has now announced that Google App Maker will be closing down in less than a year.

While the ultimate shutdown date isn't until January 2021, App Maker is now no longer being actively developed. Additionally, Google says that as of mid-April it will no longer be possible to create new apps.

Today is Data Privacy Day, and Facebook is using the occasion to try to convince its users that it cares about their privacy.

The social network says that it recognizes there is a lot of work to do to improve privacy protections, but that's not going to stop the company from trying to make it seem as though it doesn't represent a massive invasion of privacy. As part of its latest PR campaign, Facebook will encourage users to review their privacy settings as well as launching the Off-Facebook Activity tool globally.
