Microsoft Internet Explorer contains a vulnerability that could be exploited when handling drag and drop operations. According to Microsoft Security Bulletin ms06-072:

An attacker could exploit the vulnerability by constructing a specially crafted Web page that could allow for information disclosure of cached content in the Temporary Internet Files (TIF) folder if a user viewed and interacted with the Web page.

A remote, unauthenticated attacker may be able to access arbitrary files within the Temporary Internet Files folder.

Update

Microsoft has released an update to address this issue. See Microsoft Security Bulletin ms06-072 for more details.

Disable Drag and Drop

Disable Microsoft Internet Explorer's “Drag and Drop or copy and paste files” feature as discribed in Microsoft Security Bulletin ms06-072.

Disable scripting

Disable scripting as specified in the Securing Your Web Browser document and the Malicious Web Scripts FAQ.

Do not follow unsolicited links

In order to convince users to visit their sites, attackers often use URL encoding, IP address variations, long URLs, intentional misspellings, and other techniques to create misleading links. Do not click on unsolicited links received in email, instant messages, web forums, or internet relay chat (IRC) channels. Type URLs directly into the browser to avoid these misleading links. While these are generally good security practices, following these behaviors will not prevent exploitation of this vulnerability in all cases, particularly if a trusted site has been compromised or allows cross-site scripting.

See Microsoft Security Bulletin ms06-072 for details on workarounds.
