Microsoft je izdao reviziju sigurnosnog upozorenja oznake MS11-078, prvotno objavljene 11. listopada 2011. Izvorno upozorenje je opisivalo sigurnosnu ranjivost u paketima .NET Framework i Silverlight koja se može iskoristiti za udaljeno izvođenje programskog koda.
| Paket: | Microsoft .NET Framework 1.x, Microsoft .NET Framework 2.x, Microsoft .NET Framework 3.x, Microsoft .NET Framework 4.x, Microsoft Silverlight 4.x |
| Operacijski sustavi: | Microsoft Windows XP, Microsoft Windows Server 2003, Microsoft Windows Vista, Microsoft Windows Server 2008, Microsoft Windows 7 |
| Problem: | pogreška u programskoj komponenti |
| Iskorištavanje: | udaljeno |
| Posljedica: | proizvoljno izvršavanje programskog koda |
| Rješenje: | programska zakrpa proizvođača |
| CVE: | CVE-2011-1253 |
| Izvorni ID preporuke: | MS11-078 |
| Izvor: | Microsoft |
| Problem: | |
| Otkrivena ranjivost je uzrokovana nepravilnim nasljeđivanjem unutar klasa. Revizija je izdana zbog informativnih izmjena. |
|
| Posljedica: | |
| Navođenjem korisnika na otvaranje posebno oblikovane web stranice pomoću Internet preglednika koji podržava XBAP (eng. XAML Browser Applications) ili Silverlight, udaljeni napadač može dobiti mogućnost izvođenje proizvoljnog programskog koda. |
|
| Rješenje: | |
| Korisnicima, koji to još nisu učinili, preporuča se korištenje službene programske nadogradnje koja otklanja opisanu ranjivost. |

Microsoft Security Bulletin MS11-078 - Critical
Vulnerability in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2604930)
Published: Tuesday, October 11, 2011 | Updated: Wednesday, October 19, 2011
Version: 1.1
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft .NET Framework and Microsoft Silverlight. The vulnerability could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. The vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario. This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.
This security update is rated Critical for Microsoft .NET Framework 1.0 Service Pack 3, Microsoft .NET Framework 1.1 Service Pack 1, Microsoft .NET Framework 2.0 Service Pack 2, Microsoft .NET Framework 3.5.1, and Microsoft .NET Framework 4 on all supported editions of Microsoft Windows; and Microsoft Silverlight 4. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in which the .NET Framework restricts inheritance within classes. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically.
