Vulnerabilidade no Microsoft XML Core Services

Microsoft Security Bulletin MS07-042

[CAIS, 15.08.2007-17:47, revisão 01]

O CAIS está repassando o alerta da Microsoft, intitulado "MS07-042 - Vulnerabilidade no Microsoft XML Core Services (936227)", que trata de uma vulnerabilidade descoberta no Microsoft XML Core Services.

A vulnerabilidade de execução remota faz com que os Serviços Microsoft XML Core corrompam a memória do sistema afetado. Um atacante poderia explorar esta vulnerabilidade construindo uma página Web maliciosa que, se visitada, poderia levar à execução remota de código no sistema afetado.

Caso um atacante consiga explorar com sucesso esta vulnerabilidade, ele poderá obter o controle total sobre o sistema afetado. Entretanto, a interação do usuário é necessária para a exploração desta vulnerabilidade.

Os Serviços Microsoft XML Core (MSXML) permitem o uso de JScript, Visual Basic Scripting Edition (VBScript) e Microsoft Visual Studio 6.0 no desenvolvimento de aplicações baseadas no padrão XML 1.0.
