Severity Rating: Important
Revision Note: V2.0 (March 16, 2015): To address a connectivity issue with update 3002657 when installed on supported editions of Windows Server 2003, Microsoft released update 3002657-v2 for all supported editions of Windows Server 2003. Customers who have not already installed the 3002657 update should install update 3002657-v2 to be fully protected from this vulnerability. To avoid the possibility of future detection logic problems, Microsoft recommends that customers running Windows Server 2003 who have already successfully installed the 3002657 update also apply update 3002657-v2 even though they are already protected from this vulnerability. Customers running other Microsoft operating systems are not affected by this rerelease and do not need to take any action. See Microsoft Knowledge Base Article 3002657 for more information.
Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow spoofing if an attacker who is logged on to a domain-joined system runs a specially crafted application that could establish a connection with other domain-joined systems as the impersonated user or system. The attacker must be logged on to a domain-joined system and be able to observe network traffic.
