-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Adobe Reader. 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 Bitmap parsing component of rt3d.dll. When
allocating a destination buffer for handling 4/8-bit RLE compressed
bitmaps, the process uses the bitmap bits per pixel and number of colors
values directly. A pointer is created based on the specified color
depth, which can then be used to copy user supplied data into the
fixed-length color data buffer on the heap. A remote attacker can
exploit this vulnerability to execute arbitrary code under the context
of the user.

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