Microsoft has helped Adobe repel the Zero-day PDF Viewer Exploit attacks by asking Windows users to block ongoing attacks using a Microsoft enterprise tool. Adobe issued a security warning last week that the vulnerability was being actively exploited and could allow attackers to take control of victims’ computers.
The threat exists in Adobe Reader 9.3.4 and earlier versions for Windows, Macintosh and Unix, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh.
Adobe has released a mitigation tool for the latest zero-day vulnerability in its Reader and Acrobat products that will will help protect users until a patch is available, which may be released before the next scheduled security update on 12 October.
