If you use Zoom on a Windows PC, it is time to check for updates. The company has released new packages that close two serious security holes in the Windows version of its meeting software.

Both flaws allow what security people call privilege escalation. In plain terms, someone who already has a foothold with limited rights could end up with more control over the machine than they should have. The reported attack route is over the network, so an attacker does not need to sit at your keyboard.

What is the Zoom for Windows vulnerability?

According to the information available, there are two separate vulnerabilities, both rated as serious, and both affect the Windows client. Zoom fixed them with updated installation packages. Details such as version numbers or technical specifics were not part of the material we have, so we are not guessing at them here.

Do you need to update Zoom?

Yes, if you run the Windows client. Privilege escalation bugs are rarely the first step of an attack, but they are what turns a small break-in into a bigger one. Installing the current Zoom package is the straightforward fix, and the same goes for any company that rolls out Zoom to employees centrally: the patched packages need to be distributed.

Zoom is on a great many work and home computers, which is why even flaws that need some preconditions get attention. Updating takes a few minutes and removes the problem.
