Microsoft Internet Explorer Multiple Vulnerabilities ( 09 June 2010 )

1. Cross-Domain Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that Internet Explorer caches data and incorrectly allows the cached content to be called, potentially bypassing Internet Explorer domain restriction. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page. An attacker who successfully exploited this vulnerability could view content from the local computer or a browser window in another domain or Internet Explorer zone.

2. toStaticHTML Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that Internet Explorer handles content using specific strings when sanitizing HTML. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow information disclosure if a user viewed the Web page. An attacker who successfully exploited this vulnerability could inflict cross-site scripting on the user, allowing the attacker to execute script in the user's security context against a site that is using the toStaticHTML API.

3. Uninitialized Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

4. HTML Element Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted in the IE8 Developer Toolbar. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

5. Uninitialized Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted in the IE8 Developer Toolbar. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

6. Memory Corruption Vulnerability

A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. An attacker could exploit the vulnerability by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
