Apple sent a couple of updates to my Macs. Once for QuickTime and one for GarageBand.
QuickTime 7.3.1 is available through Apple automatic update and a standalone download in four different versions. One for Windows, one for Panther, one for Tiger and one for Leopard. The QuickTime update contains three security fixes. All three vulnerabilities could allow arbitrary code execution.
While not a security update, GarageBand 4.1.1 was also released. It has the terse description: “This update improves overall stability and addresses issues with file export to iPhone.”
I watched a couple of QuickTime movies and streamed a couple more videos without any problems.
