-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-080 : Adobe Flash Player MP4 Stream Decoding Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-080 June 6, 2012 - -- CVE ID: CVE-2012-0754 - -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P - -- Affected Vendors: Adobe - -- Affected Products: Adobe Flash Player - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12273. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash 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 parsing of MP4 files. A size value is read from MP4 files and used for size calculation without proper validation. The arithmetic performed on the size value can cause integer overflows, resulting in undersized allocations. This undersized memory allocation can be subsequently overpopulated with data supplied by the input file which can be used to gain remote code execution under the context of the current process. - -- Vendor Response: Adobe has issued an update to correct this vulnerability. More details can be found at: http://www.adobe.com/support/security/bulletins/apsb12-03.html - -- Disclosure Timeline: 2012-01-12 - Vulnerability reported to vendor 2012-06-06 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Alexander Gavrun - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.
