Don’t worry about CurveBall just yet — get your Citrix systems patched

Credit to Author: Woody Leonhard| Date: Tue, 21 Jan 2020 08:03:00 -0800

Hey, admins! It’s been an exciting week, eh?

Most of you have been inundated with requests — demands — that you patch all of your systems immediately to protect them from the highly publicized CVE-2020-0601 Crypt32.dll security hole, known as “Chain Of Fools” or “CurveBall.” 

While you were scrambling to comply with the NSA’s unique advertising, abetted by almost every security expert on the planet, a funny thing happened. There are no in-the-wild exploits for the ol’ CurveBall. But there are lots and lots of Citrix ADC and Citrix Gateway systems under attack, using a security hole announced in December called CVE-2019-19781.

If you want to install the January Patch Tuesday patches, by all means, go right ahead. That said, I continue to recommend that you hold off installing the January Microsoft patches until we get a clearer reading on potential bugs.

The pro-patch-now argument generally goes something like this: Everybody is recommending that you install the patches to protect against the Crypto bug — almost all of the major security folks, the researchers, the big online sites, your local news station, your congresscritter, your neighbor’s nine-year-old, even the bleeping NSA. It’s a little patch. Why not just install it and be done with it?

No, Windows 7 isn’t dead.

No, you don’t need to buy a Win10 computer. 

No, you don’t need to upgrade.

No, you don’t need to install the latest Win7 patches right away.

No, Microsoft isn’t withdrawing its unofficial nod-and-a-wink free upgrade from Win7 to Win10. At least, not right away.

No, the old Win7 patches aren’t disappearing.

No, your Internet Service Provider won’t kick you off your network for using Win7.

Patch Tuesday aftermath: The NSA Crypt32 threat is real, but not yet imminent

Credit to Author: Woody Leonhard| Date: Wed, 15 Jan 2020 07:26:00 -0800

Get ready for your local news station’s weather reporter to start lecturing on the importance of installing Windows patches.

Yesterday we were treated to a remarkable Patch Tuesday. “Remarkable” specifically in the sense that the U.S. National Security Agency was moved to put out a press release (PDF):

NSA recommends installing all January 2020 Patch Tuesday patches as soon as possible to effectively mitigate the vulnerability on all Windows 10 and Windows Server 2016/2019 systems.
