Microsoft .NET Framework Type check code execution
| dotnet-type-code-execution (48294) |  High Risk |
Description:
The Microsoft .NET Framework could allow a remote attacker to execute arbitrary code on the system, caused by a vulnerability in the way Type equality checks are handled when objects of one type are combined into another type. By persuading a victim to visit a specially-crafted Web site or execute a malicious .NET application locally, a remote attacker could exploit this vulnerability to overwrite memory and execute arbitrary code on the system with the privileges of the victim.
