Windows Updates issue (October 8 2013 updates) RRS feed

  • Question

  • We have set of business entitles which are serialized using XML serialization and that XML is encrypted using TripleDESCryptoServiceProvider() .NET API and stored in SQL server database. 
    Everything was working fine.
    On 10/10/2013 suddenly we observed that our application started throwing attached error and stopped working.
    After lot of investigation we found that our application is unable to decrypt previously encrypted XML data stored in Database.
    Above problem is reproduced at various user production sites and they are unable to use our application.
    This problem is critical as our users are unable to  use our application.
    After lot of RND we found that one of the critical windows auto update installed on 09/10/2013 or 10/10/2013 (attached as a sample) is causing the problem.
    i.e. After roll backing these updates or reinstalling .NET 4.0 framework does resolve this critical problem.
    Currently we are handing above issue at our customer's live environment on case to case basis.
    We need to find out proper solution for above problem as soon as possible. Please help us to resolve above critical issue as soon as possible.
