TPTI-11-02: Adobe Shockwave TextXtra Invalid Seek Remote Code Execution Vulnerability http://dvlabs.tippingpoint.com/advisory/TPTI-11-02 February 8, 2011 -- CVE ID: CVE-2011-0555 -- 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 Adobe Shockwave. 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 a DEMX RIFF chunk within Director files. The logic within the TextXtra.x32 module fails to account for a specific condition and can be made to misallocate a buffer on the heap. By crafting specific values within DEMX substructures an attacker can corrupt memory leading to arbitrary code execution 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: http://www.adobe.com/support/security/bulletins/apsb11-01.html -- Disclosure Timeline: 2010-12-16 - Vulnerability reported to vendor 2011-02-08 - Coordinated public release of advisory -- Credit: This vulnerability was discovered by: * Logan Brown, TippingPoint DVLabs
