TITLE

Adobe Reader and Acrobat Vulnerable to arbitrary code execution

DESCRIPTION

Adobe Reader and Acrobat before 9.5, and 10.x before 10.1.2, on Windows and Mac OS X allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2011-4370 and CVE-2011-4372. 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 2d.x3d, which is Adobe Reader's code responsible for processing BMP files. When passing a negative size parameter in the 'colors' field, a series of signed comparisons will be averted, and the overly large size parameter is passed to a memcpy(). Failed exploit attempts will likely cause denial-of-service conditions. Adobe Reader and Acrobat Both Adobe Adobe ) company's products. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-021 : Adobe Reader BMP Resource Signedness Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-021 February 8, 2012 - -- CVE ID: CVE-2011-4373 - -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P - -- Affected Vendors: Adobe - -- Affected Products: Adobe Reader - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12017. - -- Vendor Response: Adobe has issued an update to correct this vulnerability.
