ZDI-11-296 : Adobe Reader BMP Image RLE Decoding Remote Code Execution
Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-11-296
October 26, 2011

-- CVE ID:
CVE-2011-2438

-- 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 Adobe Image parsing library. When
Adobe Reader tries to parse an malformed .BMP image containing Run
Length Encoded data it fails to perform sufficient boundary checks on
the data. The effect can be a heap buffer overflow resulting in remote
code execution under the context of the current user.

-- Vendor Response:

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