February 8, 2011

-- CVE ID:
CVE-2011-0600

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

-- Affected Vendors:
Adobe

-- Affected Products:
Adobe Reader

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

The flaw exists within the U3D component distributed with the Reader.
The application uses the Parent Node count to calculate the size of an
allocation. This value is not properly validated and the result of this
size calculation can be wrapped to an unexpectedly small and
insufficient value. Writes to this newly allocated buffer can be outside
the bounds of its allocation. A remote attacker can exploit this
vulnerability to execute arbitrary code under the context of the
application. 

-- Vendor Response:
Adobe has issued an update to correct this vulnerability. More
