TITLE:
Microsoft .NET Framework / Silverlight Code Execution
Vulnerabilities
Criticality level: Highly critical
Impact: System access
Where: From remote
VERIFY ADVISORY:
http://secunia.com/advisories/40872/
DESCRIPTION:
Some vulnerabilities have been reported in Microsoft .NET
Framework
and Silverlight, which can be exploited by malicious people to
compromise a vulnerable system.
1) An error in the way Silverlight handles pointers can be
exploited
to corrupt memory by tricking a user into visiting a web site
containing specially crafted Silverlight content.
Successful exploitation allows execution of arbitrary code.
NOTE: This vulnerability affects Silverlight 3 only.
2) An error in the .NET Framework when the CLR (Common Language
Runtime) handles delegates to virtual methods can be exploited
by a
specially crafted .NET application or Silverlight application
to
execute arbitrary unmanaged code.
SOLUTION:
Apply patches.
