Tomorrow at the Black Hat USA conference in Las Vegas, James Forshaw, a Principal Security Consultant at Context Information Security, will be presenting details of vulnerabilities discovered in the .NET framework that allow malicious remote code execution from within .NET applications. His paper, 'Breaking .NET Through Serialization' is also published today at: www.contextis.co.uk/research/white-papers/areyoumytype
Earlier this year, Microsoft released a patch to mitigate the risks after Context made Microsoft aware of the .NET vulnerabilities and helped to fix the issues. The patch makes changes to the workings of the serialization framework, a fundamental feature of .NET applications that allows data nr sndwjae nl xc bkintw qffnwnflnra jww dlimtl.
