Zoom has identified a vulnerability in its Zoom Meeting Client for Mac, Windows and Linux.  This vulnerability is pretty bad, we believe it’s worth you taking the time to upgrade.  The vulnerability could enable execution of unauthorized Zoom commands like spoofing chat messages, hijacking screen controls and kicking attendees off calls and locking them out of meetings.

To address this issue, Zoom has released updated Zoom Meeting Clients for Mac, Windows, Linux, iOS, and Android.  Make sure your client is one of these versions:

  • Windows: 4.1.34460.1105 or higher
  • Mac: 4.1.34475.1105 or higher
  • Linux: 2.5.146186.1130 or higher
  • IOS: 4.1.18 (4460.1105) or higher
  • Android: 4.1.34489.1105 or higher


What you should do:

Zoom users should download and install the most recent version of the Zoom Meeting Client.  The update is available here: https://lbnl.zoom.us/download.



Why would this article be featured in IT Spotlight? The Green Gaming Project was a collaboration between Science and IT. Evan Mills and Norm Bourassa, senior scientists from the Building Technology and Urban Systems Division, worked together with a group of avid gamers from the IT Workstation Support Group to measure the energy consumption from gaming systems. This project and IT’s Jimmy Mai’s involvement were recently highlighted in Mother Jones, Video Games Consume More Electricity Than 25 Power Plants Can Produce.

The story began when Evan Mills brought in his MacBook Pro to be repaired by the IT Workstation Support Group. Evan shared his story about measuring energy consumption on his son’s gaming PC. The IT technicians, some avid gamers, engaged in the conversation and were curious about his work. One thing led to another and Mills found a group of willing participants in his project. He had IT staff designing, procuring, configuring, testing and monitoring gaming systems plus the development of server and client software to track GPU consumption since it was not available in the open market. The Workstation Support Group became the one stop shop for Mills and Bourassa and this project became the dream job for Desktop Systems Specialist Jimmy Mai, the lead tester on the project. It was a win-win for the Lab.

Operations computers are managed by the IT Workstation Support Group under the Operations Desktop Support (ODS) program. At this time Operations Mac users cannot install the latest macOS, Mojave. We are currently blocking this macOS until we can confirm that all standard ODS software is compatible with the upgrade. Test results indicate that all software works except for Spirion, a Personal Identifying Information (PII) removal tool. We are waiting on the vendor to release an update. Delivery date not yet published. Once a Spirion update is provided, ODS Mac users will be able to download and install Mojave.

For non-Operations users, always approach major operating system upgrades with caution. Users should always verify:

  • Hardware compatibility
  • Application compatibility
  • Backup capability

RoaringApps (https://roaringapps.com/), a crowd sourcing website provides information on application compatibility with operating system versions. All Mac users should ensure they have a backup of their system before doing any kind of update to minimize downtime if the upgrade fails.

If for some reason you need to help updating your Mac, REQUEST HELP.
