DESCRIPTION:
Two vulnerabilities have been reported in Microsoft .NET Framework,
which can be exploited by malicious people to compromise a user's
system.

1) An error within the .NET Framework does not properly serialize
user input and can be exploited to treat untrusted input as trusted.

2) An error within the .NET Framework does not properly handle
exceptions when serializing objects and can be exploited via
partially trusted assemblies.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

SOLUTION:
Apply patches.
