Description


Three vulnerabilities have been reported in Microsoft Windows Vista, which can be exploited by malicious people to compromise a user's system.

1) An error in the Feed Headlines gadget when parsing HTML attributes can be exploited to execute arbitrary code via a specially crafted RSS post.

Successful exploitation requires that a user e.g. is tricked into subscribing to a malicious RSS feed in the Feed Headlines gadget using Internet Explorer.

2) An error in the Contacts Gadget when processing contacts can be exploited to execute arbitrary code when selecting a specially-crafted contact or if it is the first contact in the list.

Successful exploitation requires that a user e.g. is tricked into adding or importing a malicious contact into the Contacts Gadget (not enabled by default).

3) An error in the Weather Gadget when processing HTML attributes can be exploited to execute arbitrary code when a user e.g. clicks on a link on the affected gadget.

Successful exploitation requires a MitM (Man-in-the-Middle) attack and that the links are visible in the Weather Gadget by dragging and dropping the gadget on the desktop.
