ZDI-10-087: Adobe Shockwave Invalid Offset Memory Corruption Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-10-087 May 11, 2010

-- CVE ID: CVE-2010-1281

-- 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 in that a target visit a malicious website.

The specific flaw exists within the code responsible for parsing Director files. The vulnerable function is exported as an ordinal from the iml32.dll module. Ordinal 1409 trusts a value from the file as an offset and updates pointers accordingly. By crafting a large enough value and seeking the file pointer past the end of a buffer this can be abused to corrupt heap memory. An attacker can abuse this 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:
