Quote:Reportedly, Microsoft has issued an alert for all users regarding a vulnerability that ships with the Windows operating system. The bug exists in Adobe Type Manager Library (atmfd.dll) which facilitates rendering PostScript Type 1 fonts inside the OS.


What’s troublesome is that before catching the attention of the vendors for a fix, it attracted hackers. Hence, this vulnerability is now under active exploitation. Microsoft have noted the exploitation of this zero-day vulnerability against Windows 7.

Two remote code execution vulnerabilities exist in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi-master font – Adobe Type 1 PostScript format.

There are multiple ways an attacker could exploit the vulnerability, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane.
