For the second time in two months, adobe confirms zero day bug

For the second time in the last four weeks, Adobe has told users that hackers are exploiting an unpatched bug in Flash Player, again by embedding malicious code inside a Microsoft Office document.

In a security advisory issued Monday, Adobe said that attackers are exploiting the vulnerability by embedding Flash attack files within a Microsoft Word document sent as an email attachment.

Adobe did not spell out a patch timeline for the newest Flash zero-day. Four weeks ago, Adobe issued a similar warning about a different flaw that hackers manipulated via attack code tucked inside Excel spreadsheet attachments.

Later, RSA Security confirmed that the March vulnerability had been used by cybercriminals to gain a foothold on its corporate network, then steal information related to the company's SecurID two-factor authentication products.

Adobe today warned of a critical hole in Flash Player that is being exploited in the wild to take control of computers or cause them to crash.


"There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Word (.doc) file delivered as an email attachment, targeting the Windows platform," the company said in an advisory.

"At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing."
Adobe said it is "finalizing a schedule" for releasing updates for Flash Player 10.2.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, Adobe Acrobat X (10.0.2) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.2) for Macintosh, and Adobe Reader 9.4.3 and earlier 9.x versions for Windows and Macintosh.

Since Adobe Reader X Protected Mode would prevent an exploit of this kind from executing, the company said it will address the issue in Adobe Reader X for Windows with the next quarterly security update, scheduled for June 14.
