The company had previously defended its earlier decisions. The web server only responded to requests from the local computer, Zoom said. It argued that this was more convenient than having to confirm launching the Zoom client every time you wanted to get into a meeting. It also fixed a denial-of-service bug in May, although it didn't require an update as this was deemed a "low-risk vulnerability."

This won't be a huge issue unless you're regularly using Macs for work-related video conversations, but it promises to be a relief for the corporate crowd. It also illustrates the sheer amount of pressure to be transparent and quick about addressing security holes in the modern tech world. Researcher Jonathan Leitschuh, who discovered the flaw, noted that Zoom's newfound willingness to patch out the web service represented an "about face" -- it went from rationalizing its existing strategy to planning a fix in a matter of hours.
