Microsoft Windows XP and Vista overwrites ARP table entries included in gratuitous ARP, which allows remote attackers to cause a denial of service (loss of network access) by sending a gratuitous ARP for the address of the Vista host.

The neighbor discovery implementation in Microsoft Windows Vista allows remote attackers to conduct a redirect attack by (1) responding to queries by sending spoofed Neighbor Advertisements or (2) blindly sending Neighbor Advertisements.

The Teredo implementation in Microsoft Windows Vista uses the same nonce for communication with different UDP ports within a solicitation session, which makes it easier for remote attackers to spoof the nonce through brute force attacks.

DFSR.exe in Windows Meeting Space in Microsoft Windows Vista remains available for remote connections on TCP port 5722 for 2 minutes after Windows Meeting Space is closed, which allows remote attackers to have an unknown impact by connecting to this port during the time window.

Microsoft Windows Vista establishes a Teredo address without user action upon connection to the Internet, contrary to documentation that Teredo is inactive without user action, which increases the attack surface and allows remote attackers to communicate via Teredo.

Microsoft Internet Explorer 7.0 on Windows XP and Vista allows remote attackers to conduct phishing attacks and possibly execute arbitrary code via a res: URI to navcancl.htm with an arbitrary URL as an argument, which displays the URL in the location bar of the "Navigation Canceled" page and injects the script into the "Refresh the page" link, aka Navigation Cancel Page Spoofing Vulnerability."

Microsoft Internet Explorer 6 SP2 and earlier allows remote attackers to cause a denial of service (crash) via certain malformed HTML, possibly involving applet and base tags without required arguments, which triggers a null pointer dereference in mshtml.dll.

Microsoft Internet Explorer 6.0.2900 SP2 and earlier allows remote attackers to cause a denial of service (crash) via a table element with a CSS attribute that sets the position, which triggers an "unhandled exception" in mshtml.dll.
