Patch Tuesday Analysis for July 2007

6 Patches released today. Most are affecting workstations. One unusual exploit is affecting Active Directory. We know your DCs aren’t directly connected to the internet so you probably already have some workarounds enabled. And of course you have a firewall…Pay particular attention to Windows 2000 Server since an anonymous user with access to the network (oh no!) could deliver a specially crafted LDAP packet to the affected system in order to exploit this vulnerability. Pay particular attention to this one. If you don’t have the workarounds in place, check your firewall and/or routers quickly! This one is a good exercise for all AD admins to look at. Follow the best practices and you won’t have to hurry home from vacation. Of note too is the exploit only affecting Vista. Teredo has to do with the network address translation of IPv6 traffic. This patch involves changes to the firewall and it seems this would be easier to implement that the workarounds.
