Microsoft Internet Explorer Multiple Vulnerabilities ( 13 October 2010 )

1. AutoComplete Information Disclosure Vulnerability

An information disclosure vulnerability exists that potentially allows form data within Internet Explorer to be captured via the AutoComplete feature. 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 capture information previously entered into fields after the AutoComplete feature has been enabled.

2. HTML Sanitization Vulnerability

An information disclosure vulnerability exists in the way that the toStaticHTML API sanitizes HTML, that could allow an attacker to perform cross-site scripting attacks and run script in the security context of the logged-on user. An attacker who successfully exploited this vulnerability could execute a cross-site scripting attack 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. HTML Sanitization Vulnerability

An information disclosure vulnerability exists in the way that the toStaticHTML API sanitizes HTML, that could allow an attacker to perform cross-site scripting attacks and run script in the security context of the logged-on user. An attacker who successfully exploited this vulnerability could execute a cross-site scripting attack on the user, allowing the attacker to execute script in the user's security context against a site that is using the toStaticHTML API.

4. CSS Special Character Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that Internet Explorer processes CSS special characters. 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 another domain or Internet Explorer zone.

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. 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. Anchor Element Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that Internet Explorer improperly handles the Anchor element. This behavior occurs during user operation when the Anchor element is not removed during content pasting and editing, potentially revealing personally identifiable information intended for deletion.

7. 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.

8. 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 when a document in an HTML format is opened in Microsoft Word. An attacker could exploit the vulnerability by convincing the user to open a malicious Word document. When a user closes the document, 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.

9. Cross-Domain Information Disclosure Vulnerability

An information disclosure vulnerability exists in Internet Explorer that could allow script to gain access to information in another domain or Internet Explorer zone. 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 another domain or Internet Explorer zone.

10. 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 convincing a user to view a specially crafted Word document. When a user closes the Word document, 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.
