-- CVE ID:
CVE-2011-2434

-- CVSS:
7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

-- Affected Vendors:

Adobe



-- Affected Products:

Adobe Reader



-- 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 specific flaw exists within the way Adobe handles PICT images. When
Adobe parses a PICT image containing an 0x0E opcode. When this opcode is
read the following word in the file will be interpreted as a loop
counter that copies data from the file into a heap buffer that has been
created using the height and with of the picture. The resulting heap
overflow can result in remote code execution under the rights of the
current user.

-- Vendor Response:

Adobe has issued an update to correct this vulnerability. More details
