Prezados,

O CAIS esta' repassando o alerta da Microsoft, intitulado "MS08-001 - 
Critical Vulnerabilities in Windows TCP/IP Could Allow Remote Code 
Execution (941644)", que trata de duas vulnerabilidades encontradas no 
processamento do protocolo TCP/IP (Transmission Control Protocol/Internet 
Protocol).

Estas vulnerabilidades existem devido 'a maneira como o kernel do Windows 
processa estruturas TCP/IP que contem solicitacoes multicast ou ICMP.

A exploracao destas vulnerabilidades pode levar o sistema a uma condicao 
de negacao de servico (DoS) ou pode ainda permitir a execucao remota de 
codigo.
