Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities in the Microsoft .NET Framework :

  • An elevation of privilege vulnerability exists due to improper validation of the number of objects in memory before they are copied into an array. A remote, unauthenticated attacker can exploit this to bypass Code Access Security (CAS) restrictions by convincing a user to run an untrusted .NET application or to visit a website containing a malicious XAML browser application. (CVE-2015-2504)

  • A denial of service vulnerability exists due to improper handling of specially crafted requests to an ASP .NET server. A remote, unauthenticated attacker can exploit this to degrade performance. (CVE-2015-2526)
