Security Advisory

1) Denial of service

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to improper comparison of the value of an index within a WPF application in .NET Framework. A remote attacker can send a specially crafted request and cause the application to stop responding until a manual restart.

Successful exploitation of the vulnerability results in denial of service on the vulnerable system.
