TPTI-10-13: Adobe Shockwave Director tSAC Chunk Remote Code Execution Vulnerability http://dvlabs.tippingpoint.com/advisory/TPTI-10-13 August 24, 2010 -- CVE ID: CVE-2010-2866 -- CVSS: 10, (AV:N/AC:L/Au:N/C:C/I:C/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 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 Director's RIFF-based file format. While parsing the tSAC chunk, the DIRAPI module does not properly verify the signedness of a count value within an undocumented structure. By providing a large enough negative value a pointer can be miscalculated leading to memory corruption. This can be exploited by a remote attacker to execute arbitrary code under the context of the user running the web browser. -- Vendor Response: Adobe has issued an update to correct this vulnerability. More details can be found at: http://www.adobe.com/support/security/bulletins/apsb10-20.html -- Disclosure Timeline: 2010-05-27 - Vulnerability reported to vendor 2010-08-24 - Coordinated public release of advisory -- Credit: This vulnerability was discovered by: * TippingPoint FuzzBox as driven by Aaron Portnoy and Logan Brown
