SUBJECT: Multiple Vulnerabilities in Adobe Flash Player Could Allow For Remote Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player and AIR that could allow an attacker to take control of the affected system. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages.

Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

It should be noted that these vulnerabilities are currently being exploited via various phishing campaigns.

DESCRIPTION:

Adobe Flash Player and AIR are prone to multiple vulnerabilities that could allow for remote code execution. Adobe has released security updates for Adobe Flash Player 11.5.502.146 and earlier versions for Windows and Macintosh, Adobe Flash Player 11.2.202.261 and earlier versions for Linux, Adobe Flash Player 11.1.115.36 and earlier versions for Android 4.x, and Adobe Flash Player 11.1.111.31 and earlier versions for Android 3.x and 2.x. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

CVE-2013-0633 - This vulnerability is being exploited in the wild in targeted attacks designed to trick the users into opening a Microsoft Word document delivered as an email attachment which contains malicious Flash (SWF) content. The exploit targets the ActiveX version of Flash Player on Windows.

CVE-2013-0634 - This vulnerability is being exploited in the wild in attacks delivered via malicious Flash (SWF) content hosted on websites that target Flash Player in Firefox or Safari on the Macintosh platform, as well as attacks designed to trick Windows users into opening a Microsoft Word document delivered as an email attachment which contains malicious Flash (SWF) content.
