Have you updated Flash recently? Even if you have, you might want to make sure you’re up to date, as yesterday Adobe issued an emergency patch addressing several critical vulnerabilities that the company says “could potentially allow an attacker to take control of the affected system.”

The vulnerabilities affect those using the plugin in Windows, Mac, and Linux, including those versions provided in browsers like Chrome. And at least one of these bugs is currently known to those who walk on the darker side of the Web, with Adobe saying that the patch fixes an exploit that is being used in “limited, targeted attacks.”

While that exploit is singled out as particularly nasty since it can be triggered simply by visiting the wrong website, the rest could be just as dangerous. The vulnerabilities include “13 use-after-free vulnerabilities, four memory corruption vulnerabilities, and one type-confusion vulnerability,” as noted by CSO.

If you’re running anything earlier than Flash version 20.0.0.267, you’ll need to update. If you aren’t sure, head over to Adobe’s About Flash Player page, which will show you the version you’re running. The security bulletin issued by the company provides instructions on how to update the software.

This is far from the first time this year that such a patch has been released. Earlier this year we reported that the Italian spyware firm Hacking Team had itself been hacked. Among the files distributed as a result were multiple major security flaws in Flash that the group had kept to itself in order to use in its work.

These types of vulnerabilities, along with improvements in various alternative Web technologies, have led to many companies deciding to abandon Flash as a whole. Several sites including YouTube have dropped Flash in favor of HTML5 video, while in July, Facebook’s security chief called for Adobe to set an end-of-life date for the aging technology.

It seems that 2015 may have been the beginning of the end for Flash, but what does 2016 hold in store?

Usually $1,500, this HP gaming PC with an RTX 4070 is $800 today

While gaming laptops tend to get all the love and attention these days, that doesn't mean that the gaming desktop market hasn't also been booming quite significantly. It used to be that you had to build your PC from scratch or buy from a boutique seller, but now even the big brands have gotten into the pre-built gaming PC market. One great example is the Omen 40L gaming desktop from HP, with this entry-level configuration going for just $800 rather than the usual $1,500, which amounts to a whopping $700 discount.

Why you should buy the OMEN 40L Gaming Desktop
The Omen 40L has a lot of configurations to pick from, and while they aren't all a great deal, this one starts on an excellent foundation. At the heart of the build is an RTX 4060, an excellent 1080p GPU that should handle most modern games just fine with high graphical fidelity and above 100 frames per second. That said, you can do quite a few upgrades in the Customizer, and probably one of the better options would be the RTX 4060 Ti for an extra $160, although if you're willing to spend all of the discount, you could also potentially go for an RTX 4080 for $990.

Get this HP 17-inch laptop for $300 instead of the usual $660

Seventeen-inch laptops toe the line between portability and size, making them more expensive than your average laptop. Some of the best 17-inch laptops can easily cost you thousands of dollars. Luckily, there HP has come up with a very budget-friendly solution in the form of the HP laptop 17z, and while it's not one of the best laptops on the market, it is an excellent budget-oriented choice for a 17-inch laptop. Even better, HP currently discounts it down to $300 from the usual $560 price tag, which is a significant $260 off.

Why you should buy the HP Laptop 17z
As the name implies, the HP Laptop 17z has a large 17.3-inch screen running a 1920 x 1080 resolution and can hit a peak brightness of 250nits, which isn't a lot, but it's good enough for a well-lit room, especially with its anti-glare coating. You could potentially upgrade to a touch version of the screen for $30, but since it would knock the resolution down to 1600 x 900, it's not worth it, especially with a larger 17.3-inch screen. What will be worth the upgrade is taking the networking option from the Wi-Fi5 and Bluetooth 4.2 standard up to the Wi-Fi 6 and Bluetooth 5 standard for an extra $20, which will make sure your laptop has a strong connection for streaming or doing online meetings and will be future-proof for at least the next 5-6 years.
