Latest Advisories Notable Vulnerabilities

  • Vulnerabilities in .NET Framework Could Allow Elevation of Privilege (2638420)
     Severity: :    
     Advisory Date:  30 December 2011

    This security update addresses one publicly and three privately disclosed vulnerabilities in Microsoft .NET Framework.
