CVE-2010-3228
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe JIT compiler in Microsoft .NET Framework 4.0 on 64-bit platforms does not properly perform optimizations, which allows remote attackers to execute arbitrary code via a crafted .NET application that triggers memory corruption, aka ".NET Framework x64 JIT Compiler Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe JIT (Just-In-Time) compiler in Microsoft .NET Framework 4.0 on 64-bit platforms contains a vulnerability due to improper optimization logic. This flaw causes memory corruption when specially crafted .NET applications are executed, allowing attackers to potentially achieve remote code execution with the privileges of the running application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify .NET Framework 4.0 is installedRun: reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" /v Version or check in Programs and Features for Microsoft .NET Framework 4.0Affected if The registry key exists and shows Version 4.0.30319 (initial release) without any subsequent servicing updates installed
-
Confirm the system architecture is 64-bitRun: systeminfo | findstr "System Type" or check if %PROCESSOR_ARCHITECTURE% equals AMD64Affected if System reports x64-based PC or PROCESSOR_ARCHITECTURE shows AMD64 - only 64-bit systems are affected
-
Identify exact .NET 4.0 servicing versionCheck the Release value in registry key HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full; initial RTM release value is 30319Affected if Release value is 30319 (RTM) - this indicates the unpatched version; values above 30319 indicate patches applied (patched versions are not affected)
-
Check for installed security updatesRun: wmic qfe list or check Windows Update history for MS10-041 installationAffected if No MS10-041 or subsequent .NET 4.0 security updates are present, leaving the JIT vulnerability unmitigated
A system is affected only if it runs .NET Framework 4.0 RTM (version 4.0.30319) on a 64-bit Windows platform and has not received the MS10-041 patch or later servicing update.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Microsoft security patch MS10-041 (or subsequent relevant patches) to all affected 64-bit systems running .NET Framework 4.0. Prioritize patching internet-facing servers and high-privilege application hosts.
