Firefox disconnected from "dangerous" WPF

    On Saturday morning, many Firefox users saw a message about disabling the Windows Presentation Foundation plugin, which is said to be "a security risk."

    Mozilla developers soon explained that the .NET Framework Assistant plug-in and the sister Windows Presentation Foundation, through a centralized locking mechanism, had actually been massively disabled . This is due to a serious vulnerability identified in June . Microsoft itself recommends that its users disable the .NET Framework Assistant if they have not installed a patch for IE.

    Microsoft was previously notified of the actions of Mozilla and gave the go-ahead, so that the locking mechanism was launched on Saturday at about 5:00 am Moscow time.

    Soon, Microsoft representatives again contacted. They informed that the .NET Framework Assistant plugin does not actually pose a security risk and cannot be used to launch exploits of the aforementioned vulnerability. Immediately after this, the .NET Framework Assistant was unlocked . Thus, his quarantine lasted only about 48 hours. But the second Windows Presentation Foundation plugin is still blacklisted.

    If it seemed to you that you did not install such a plug-in in your browser, then keep in mind that the .NET Framework Assistant penetrated Firefox relatively quietly during the February Windows update (this was already discussed on Habré).
