Hackers can take advantage of exposed Zoom vulnerabilities quickly, Goodin noted, if Zoom users aren't updated right away. Ars' Dan Goodin noted that his Zoom client didn't actually update when the fix for that issue arrived, requiring a manual download of an intermediate version first. Last May, a Zoom vulnerability that enabled a zero-click remote code execution used a similar downgrade and signature-check bypass. Prior to that, Zoom was caught running an entire undocumented web server on Macs, causing Apple to issue its own silent update to kill the server.

Wardle previously revealed a Zoom vulnerability that let attackers steal Windows credentials by sending a string of text. The company settled with the FTC in 2020 after admitting that it lied for years about offering end-to-end encryption. Zoom's software security record is spotty-and at times, downright scary. ( Update: Clarified Wardle's disclosure and update timing). You can download the update directly from Zoom or click on your menu bar options to 'Check for updates.' We wouldn't suggest waiting for an automatic update, for multiple reasons. Zoom issued a security bulletin later that same day, and a patch for version Zoom 5.11.5 (9788) followed soon after. Not only that, but this app has all kinds of calling.

Zoom is a Mac program that offers high-quality video calls and remote conferences. Zoom has had 14 updates within the past 6 months. Wardle disclosed his findings to Zoom before his talk, and some aspects of the vulnerability were addressed, but key root access was still available as of Wardle's talk on Saturday.
