Nortel Contivity VPN Client 2.1.7, 3.00, 3.01, 4.91, and 5.01, when opening a VPN tunnel, does not check the gateway certificate until after a dialog box has been displayed to the user, which creates a race condition that allows remote attackers to perform a man-in-the-middle (MITM) attack.

The Windows Animated Cursor (ANI) capability in Windows NT, Windows 2000 through SP4, Windows XP through SP1, and Windows 2003 allow remote attackers to cause a denial of service via (1) the frame number set to zero, which causes an invalid memory address to be used and leads to a kernel crash, or (2) the rate number set to zero, which leads to resource exhaustion and hang.

Nortel Alteon ACEdirector WebOS 9.0, with the Server Load Balancing (SLB) and Cookie-Based Persistence features enabled, allows remote attackers to determine the real IP address of a web server with a half-closed session, which causes ACEdirector to send packets from the server without changing the address to the virtual IP address.
