Microsoft has lent support to Adobe to block the PDF zero day exploit revealed last week.
The software giant has urged Windows users to use its enterprise tool kit, Enhanced Mitigation Experience Toolkit (EMET), to prevent their systems from being exploited by the vulnerability, tech news site Computer World reports.
Microsoft has said that EMET is a stop gap tool which will prevent attacks on older versions of Reader and Acrobat until Adobe comes up with a patch update.
Last week, Adobe issued an advisory about the bug, warning that it was being exploited by hackers in wild.
The flaw has been labelled as critical and if exploited can allow hackers to take over the control of the system.
The threat exists in Adobe Reader and Acrobat 9.3.4 and earlier versions for Windows, Mac and Unix.
Adobe has referred users to the solution link provided by Microsoft, asking them to rely on the EMET tool until Adobe releases a security update, scheduled for 12 October.
