Re: [Full-disclosure] ZDI-11-208: Adobe Shockwave rcsL Parsing Remote Code Execution Vulnerability



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

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

http://www.zerodayinitiative.com/advisories/ZDI-11-208

June 14, 2011

-- 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:
