This signature detects attempts to exploit a known vulnerability in Microsoft's .NET Framework. It is due to an error in calculating a buffer length for percent-encoded URI components of a UTF-8 encoded URI. Remote attackers could exploit this vulnerability by enticing a target user to either download and execute a malicious XAML browser application, or download and execute a malicious .NET application. A successful exploitation attempt could result in the execution of arbitrary code in the security context in which the .NET application runs.
Microsoft Silverlight and Microsoft .NET Framework are prone to a remote code-execution vulnerability. Successful exploits will allow an attacker to execute arbitrary code within the context of the affected application. Failed exploit attempts will likely result in a denial-of-service condition.
