Re: ZDI-11-208: Adobe Shockwave rcsL Parsing Remote Code Execution Vulnerability

["Mikhail A. Utin" <mutin () commonwealthcare org>]

I see numerous announcements from ZDI pointing to June 14th updates. Is that what big guys MS and Adobe missed in last 
week updates? If NO, then we need to stop ZDI from polluting our list with last year news. Anyway, I see repetitive 
announcements pretty often.
Thank you

-- CVE ID:
CVE-2011-2109

7.5, (AV:N/AC:L/Au:N/C:P/I:P/A:P)

-- Affected Vendors:
Adobe

-- Affected Products:
Adobe Shockwave Player

TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 
11370.

-- 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 rcsL chunk inside Adobe's RIFF-based Director file format. The code within the 
Dirapi.dll is affected by an integer wrap caused by size values being calculated without proper checking. This can lead 
to memory corruption which 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 details can be found at:
