CVE-2007-2223 – Microsoft Internet Explorer substringData Heap Overflow Vulnerability

https://notcve.org/view.php?id=CVE-2007-2223

Microsoft XML Core Services (MSXML) 3.0 through 6.0 allows remote attackers to execute arbitrary code via the substringData method on a (1) TextNode or (2) XMLDOM object, which causes an integer overflow that leads to a buffer overflow. Microsoft XML Core Services (MSXML) versión 3.0 hasta 6.0 permite a los atacantes remotos ejecutar código arbitrario por medio del método substringData en un objeto (1) TextNode o (2) XMLDOM, lo que provoca un desbordamiento de enteros que conduce a un desbordamiento de búfer. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of various Microsoft software User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the substringData() method available on the TextNode JavaScript object. When specific parameters are passed to the method, an integer overflow occurs causing incorrect memory allocation. If this event occurs after a different ActiveX object has been instantiated, an exploitable condition is created when the ActiveX object is deallocated which can result in the execution of arbitrary code. • https://www.exploit-db.com/exploits/30493 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=576 http://secunia.com/advisories/26447 http://www.kb.cert.org/vuls/id/361968 http://www.securityfocus.com/archive/1/476527/100/0/threaded http://www.securityfocus.com/archive/1/476747/100/0/threaded http://www.securityfocus.com/bid/25301 http://www.securitytracker.com/id?1018559 http://www.vupen.com/english/advisories/2007/2866 http://www.zerodayinitiative.com/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
