DESCRIPTION:
Multiple vulnerabilities have been reported in Microsoft .NET
Framework, which can be exploited by malicious people to disclose
potentially sensitive information, bypass certain security
restrictions, and compromise a user's system.
1) An error within permissions checking of objects that perform
reflection can be exploited via a specially crafted XAML Browser
Application (XBAP) or an untrusted .NET application.
2) A sanitisation error when processing partially trusted code can be
exploited to disclose certain data via a specially crafted XAML
Browser Application (XBAP) or an untrusted .NET application.
3) The Entity Framework component loads certain libraries in an
insecure manner, which can be exploited to load arbitrary libraries
by tricking a user into opening certain files located on a remote
WebDAV or SMB share.
4) A validation error when acquiring proxy settings via the Web Proxy
Auto-Discovery (WPAD) can be exploited to execute JavaScript code with
reduced restrictions.
5) An error within permissions checking of Windows Presentation
Foundation (WPF) objects that perform reflection can be exploited via
a specially crafted XAML Browser Application (XBAP) or an untrusted
.NET application.
SOLUTION:
Apply patches.
