Use-after-free vulnerability in the CAttrArray::PrivateFind function in mshtml.dll in Microsoft Internet Explorer 6 through 8 allows remote attackers to execute arbitrary code by setting an unspecified property of a stylesheet object, aka "Uninitialized Memory Corruption Vulnerability." Vulnerabilidad de Uso de la Memoria Previamente Liberada en la función CAttrArray::PrivateFind en la biblioteca mshtml.dll en Microsoft Internet Explorer versión 6 hasta la versión 8 permite a los atacantes remotos ejecutar código arbitrario mediante el establecimiento de una propiedad no especificada de un objeto StyleSheet, también se conoce como "Uninitialized Memory Corruption Vulnerability". This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. 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 function CAttrArray::PrivateFind as defined in mshtml.dll. If a specific property of a stylesheet object is set, the code within mshtml can be forced to free an object which is subsequently accessed later. • http://support.avaya.com/css/P8/documents/100113324 http://www.securityfocus.com/bid/43705 http://www.us-cert.gov/cas/techalerts/TA10-285A.html http://www.zerodayinitiative.com/advisories/ZDI-10-197 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-071 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A7059 • CWE-416: Use After Free •

The CTimeoutEventList::InsertIntoTimeoutList function in Microsoft mshtml.dll uses a certain pointer value as part of producing Timer ID values for the setTimeout and setInterval methods in VBScript and JScript, which allows remote attackers to obtain sensitive information about the heap memory addresses used by an application, as demonstrated by the Internet Explorer 8 application. La función CTimeoutEventList::InsertIntoTimeoutList en el fichero mshtml.dll de Microsoft utiliza un valor de puntero para producir de valores de identificación a partir de un temporizador para los métodos setTimeout y setInterval en VBScript y JScript, lo que permite a atacantes remotos obtener información sensible acerca de las direcciones de la memoria 'heap' usada por una aplicación, como lo demuestra la aplicación Internet Explorer 8. • https://www.exploit-db.com/exploits/14295 http://archives.neohapsis.com/archives/bugtraq/2010-06/0259.html http://twitter.com/WisecWisec/statuses/17254776077 http://www.eeye.com/Resources/Security-Center/Research/Zero-Day-Tracker/2010/20100630 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11606 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The toStaticHTML function in Microsoft Internet Explorer 8, and the SafeHTML function in Microsoft Windows SharePoint Services 3.0 SP2, SharePoint Foundation 2010, Office SharePoint Server 2007 SP2, Groove Server 2010, and Office Web Apps, allows remote attackers to bypass the cross-site scripting (XSS) protection mechanism and conduct XSS attacks via a crafted use of the Cascading Style Sheets (CSS) @import rule, aka "HTML Sanitization Vulnerability," a different vulnerability than CVE-2010-1257. La función toStaticHTML en Internet Explorer 8 de Microsoft y la función SafeHTML en Windows SharePoint Services versión 3.0 SP2, SharePoint Foundation 2010, Office SharePoint Server 2007 SP2, Groove Server 2010 y Office Web Apps de Microsoft, permite a los atacantes remotos omitir el mecanismo de protección de cross-site scripting (XSS) y conducir ataques de tipo XSS por medio de un uso especialmente diseñado de la regla @import de Hojas de Estilo en Cascada (CSS), también se conoce como "HTML Sanitization Vulnerability", una vulnerabilidad diferente de CVE-2010-1257. • https://www.exploit-db.com/exploits/34478 http://archives.neohapsis.com/archives/fulldisclosure/2010-08/0179.html http://support.avaya.com/css/P8/documents/100113324 http://www.us-cert.gov/cas/techalerts/TA10-285A.html http://www.wooyun.org/bug.php?action=view&id=189 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-071 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-072 https://oval.cisecurity.org/repository/search/definition/ • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Microsoft Internet Explorer 6, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "HTML Layout Memory Corruption Vulnerability." Microsoft Internet Explorer v6, v7, y v8 no maneja adecuadamente objetos en memoria, lo que permite a atacantes remotos ejecutar código de su elección aceediendo al objeto que (1) que no fue inicializado (2) es borrado, lo que proboca una corrupción de memoria , conocido como "Vulnerabilidad de corrupción de Memoria HTML Layout." • http://www.us-cert.gov/cas/techalerts/TA10-222A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2010/ms10-053 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11832 • CWE-787: Out-of-bounds Write •
