Uninstall QuickTime for Windows Today

If you guys don’t already know, you need to uninstall QuickTime for Windows today. Like right now. Reason being, Apple is doing away with the program from today and will no longer be releasing security updates.

Users of the program on the Windows Platform have been advised by Apple to uninstall it pronto. Before the Mac crowd begin to worry, relax – this does not apply to QuickTime on the Mac OSX.

Internet security firm Trend Micro released a statement this morning highlighting their Zero Day Initiative (a program that rewards security researchers for responsibly disclosing vulnerabilities), released two advisories that detail critical weaknesses affecting QuickTime for Windows.

More about the two advisories here: ZDI-16-241 and ZDI-16-242

The security statement from Trend Micro can be found below:

“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.

We’re not aware of any active attacks against these vulnerabilities currently. But the only way to protect your Windows systems from potential attacks against these or other vulnerabilities in Apple QuickTime now is to uninstall it. In this regard, QuickTime for Windows now joins Microsoft Windows XP and Oracle Java 6 as software that is no longer being updated to fix vulnerabilities and subject to ever increasing risk as more and more unpatched vulnerabilities are found affecting it.”

“Our TippingPoint customers have been protected against these two vulnerabilities since November 24, 2015 with filters 21918(ZDI-CAN-3401) and 21919(ZDI-CAN-3402).

However, even with protections, ultimately the right answer is to follow Apple’s guidance and uninstall QuickTime for Windows. That is the only sure way to be protected against all current and future vulnerabilities in the product now that Apple is no longer providing security updates for it.

For those that want more technical details here are the important points: both of these are heap corruption remote code execution vulnerabilities. One vulnerability occurs an attacker can write data outside of an allocated heap buffer.

The other vulnerability occurs in the stco atom where by providing an invalid index, an attacker can write data outside of an allocated heap buffer. Both vulnerabilities would require a user to visit a malicious web page or open a malicious file to exploit them. And both vulnerabilities would execute code in the security context the QuickTime player, which in most cases would be that of the logged on user.”

Both vulnerabilities have a CVSS 2.0 score of 6.8.
