Multiple memory leaks in the DataGrid control implementation in Microsoft Silverlight 4 before 4.0.60310.0 allow remote attackers to cause a denial of service (memory consumption) via an application involving (1) subscriptions to an INotifyDataErrorInfo.ErrorsChanged event or (2) a TextBlock or TextBox element.

Security readout for executives and security teams

CVE-2011-1845 is a legacy Microsoft Silverlight 4 denial-of-service issue. A specially crafted Silverlight application could trigger memory leaks in the DataGrid control and consume memory. The business risk is mostly availability and legacy-application exposure, not data theft or code execution based on the supplied sources. Exposure is likely limited to environments still running Microsoft Silverlight 4 before 4.0.60310.0, especially legacy line-of-business apps using DataGrid controls. Organizations without Silverlight runtime or Silverlight-dependent applications are unlikely to be affected. Treat this as a legacy technology cleanup and availability risk. It is not currently supported by supplied evidence as actively exploited, but remaining Silverlight dependencies should be identified and retired or updated. Mitigation focus: Identify any remaining Silverlight 4 runtime or application dependencies.; Upgrade Silverlight 4 to 4.0.60310.0 or later where still required.; Retire or isolate Silverlight-dependent legacy workflows where practical..
