A critical vulnerability exists in Flash Player 10.2.153.1
and earlier versions (Adobe Flash Player 10.2.154.25 and
earlier for Chrome users) for Windows, Macintosh, Linux
and Solaris, Adobe Flash Player 10.2.156.12 and earlier
versions for Android, and the Authplay.dll component that
ships with Adobe Reader and Acrobat X (10.0.2) and earlier
10.x and 9.x versions for Windows and Macintosh operating
systems.
This vulnerability (CVE-2011-0611) could cause a crash
and potentially allow an attacker to take control of the
affected system. There are reports that this vulnerability
is being exploited in the wild in targeted attacks via a
malicious Web page or a Flash (.swf) file embedded in a
Microsoft Word (.doc) or Microsoft Excel (.xls) file
delivered as an email attachment, targeting the Windows
platform. 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.
