ZDI-11-080: Adobe Shockwave CSWV Chunk Substructure Offset Value Remote Code Execution Vulnerability

http://www.zerodayinitiative.com/advisories/ZDI-11-080

February 8, 2011

-- CVE ID:
CVE-2010-4190

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

-- Affected Vendors:
Adobe

-- Affected Products:
Adobe Shockwave Player

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Adobe Shockwave 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 the code responsible for parsing
substructures referenced by the CSWV RIFF chunk. An offset is improperly
calculated from several elements of a substructure. By crafting a
director file in a particular way, an attacker can cause the process to
seek out of the bounds of a heap allocation. Due to the way the process
continues to manipulate memory, an attacker can force reliable
corruption that can be leveraged to execute arbitrary code under the
context of the user running the browser.

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