Description

The remote Windows host is running a version of the Microsoft .NET Framework and/or Microsoft Silverlight affected by multiple vulnerabilities :

  • Silverlight improperly handles pointers in an unspecified manner. A remote attacker could exploit this by tricking a user into viewing a web page with maliciously crafted Silverlight content. (CVE-2010-0019)

  • An unspecified vulnerability in the .NET framework can allow a specially crafted .NET or Silverlight application to access memory, resulting in arbitrary unmanaged code execution. (CVE-2010-1898)
