ZDI-11-081: Adobe Flash Player Point Object Remote Code Execution Vulnerability

February 8, 2011

-- CVE ID:
CVE-2011-0578

-- CVSS:
9, (AV:N/AC:L/Au:N/C:P/I:P/A:C)

-- Affected Vendors:
Adobe

-- Affected Products:
Adobe Flash Player

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Adobe Flash Player. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.

The specific flaw exists within construction of a specific ActionScript3
object. Due to improper type checking in the implementation of the
constructor, an alternative type can be provided as an argument to the
constructor and stored as a property. When this object is applied to a
bitmap copy, the application will corrupt memory. This can lead to code
execution under the context of the application.

-- Vendor Response:
Adobe has issued an update to correct this vulnerability. More
details can be found at:
