-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1  ZDI-12-157 : Microsoft Excel Series Record Parsing Type Mismatch Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-157 August 22, 2012  - -- CVE ID: CVE-2012-1847  - -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P  - -- Affected Vendors: Microsoft  - -- Affected Products: Microsoft Office  - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12480. 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 Microsoft Office Excel. 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 Series records. The code within Excel.exe makes an assumption about the data types within a Series record and can be made to write beyond the bounds of a heap buffer when a specific combination of fields are set to unexpected values. This corruption can be leveraged to achieve code execution under the context of the user running the application.   - -- Vendor Response: Microsoft has issued an update to correct this vulnerability. More details can be found at: https://technet.microsoft.com/en-us/security/bulletin/MS12-030  - -- Disclosure Timeline: 2012-01-24 - Vulnerability reported to vendor 2012-08-22 - Coordinated public release of advisory  - -- Credit: This vulnerability was discovered by: * Anonymous  - -- 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.
