We’re putting the word out that everyone should follow Apple’s guidance and uninstall QuickTime for Windows as soon as possible.
This is for two reasons.
First, Apple will no longer be issuing security updates for Quicktime Video Player on the Windows Platform and recommends users uninstall it. Note that this does not apply to QuickTime on Mac OSX.
Second, our Zero Day Initiative has just released two advisories ZDI-16-241 and ZDI-16-242 detailing two new, critical vulnerabilities affecting QuickTime for Windows. These advisories are being released in accordance with the Zero Day Initiative’s Disclosure Policy for when a vendor does not issue a security patch for a disclosed vulnerability. And because Apple is no longer providing security updates for QuickTime on Windows, these vulnerabilities are never going to be patched.
