An attacker could exploit this vulnerability by supplying crafted encrypted XML that is improperly validated, resulting in denial of service.\n\n## Announcement\n\nAnnouncement for this issue can be found at https://github.com/dotnet/announcements/issues/416\n\n## CVSS Details\n\n- **Version:** 3.1\n- **Severity:** High\n- **Score:** 7.5\n- **Vector:** `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H`\n- **Weakness:** CWE-121 (Stack-based Buffer Overflow)\n\n## Affected Platforms\n\n- **Platforms:** All\n- **Architectures:** All\n\n## <a name=\"affected-packages\"></a>Affected Packages\nThe vulnerability affects any Microsoft .NET project if it uses any of affected package versions listed below\n\n### <a name=\".NET 10.0\"></a>.NET 10.0\nPackage name | Affected version | Patched version\n------------ | ---------------- | -------------------------\n[System.Security.Cryptography.Xml](https://www.nuget.org/packages/System.Security.Cryptography.Xml)               | >= 10.0.0, <= 10.0.9 | 10.0.10\n\n### <a name=\".NET 9.0\"></a>.NET 9.0\nPackage name | Affected version | Patched version\n------------ | ---------------- | -------------------------\n[System.Security.Cryptography.Xml](https://www.nuget.org/packages/System.Security.Cryptography.Xml)               | >= 9.0.0, <= 9.0.17 | 9.0.18\n\n### <a name=\".NET 8.0\"></a>.NET 8.0\nPackage name | Affected version | Patched version\n------------ | ---------------- | -------------------------\n[System.Security.Cryptography.Xml](https://www.nuget.org/packages/System.Security.Cryptography.Xml)               | >= 8.0.0, <= 8.0.3 | 8.0.4\n\n## Advisory FAQ\n\n### <a name=\"how-affected\"></a>How do I know if I am affected?\n\nIf using a package listed in [affected packages](#affected-packages), you're exposed to the vulnerability.\n\n### <a name=\"how-fix\"></a>How do I fix the issue?\n\nTo update the System.Security.Cryptography.Xml NuGet package, use one of the following methods:\n\nNuGet Package Manager UI in Visual Studio:\n- Open your project in Visual Studio.\n- Right-click on your project in Solution Explorer and select \"Manage NuGet Packages...\" or navigate to \"Project > Manage NuGet Packages\".\n- In the NuGet Package Manager window, select the \"Updates\" tab. This tab lists packages with available updates from your configured package sources.\n- Select the package(s) you wish to update. You can choose a specific version from the dropdown or update to the latest available version.\n- Click the \"Update\" button.\n\nUsing the NuGet Package Manager Console in Visual Studio:\n- Open your project in Visual Studio.\n- Navigate to \"Tools > NuGet Package Manager > Package Manager Console\".\n- To update a specific package to its latest version, use the following Update-Package command:\n\n```Update-Package -Id System.Security.Cryptography.Xml```\n\nUsing the .NET CLI (Command Line Interface):\n- Open a terminal or command prompt in your project's directory.\n- To update a specific package to its latest version, use the following add package command:\n\n```dotnet add package System.Security.Cryptography.Xml```\n\nOnce you have updated the nuget package reference you must recompile and deploy your application. Additionally we recommend you update your runtime and/or SDKs, but it is not necessary to patch the vulnerability.\n\n## Other Information\n\n### Reporting Security Issues\n\nIf you have found a potential security issue in a supported version of .NET, please report it to the Microsoft Security Response Center (MSRC) via the [MSRC Researcher Portal](https://msrc.microsoft.com/report/vulnerability/new). Further information can be found in the MSRC [Report an Issue FAQ](https://www.microsoft.com/msrc/faqs-report-an-issue).\n\nSecurity reports made through MSRC may qualify for the Microsoft .NET Bounty. Details of the Microsoft .NET Bounty Program including terms and conditions are at https://aka.ms/corebounty.\n\n### Support\n\nYou can ask questions about this issue on GitHub in the .NET GitHub organization. The main repos are located at https://github.com/dotnet/runtime. The Announcements repo (https://github.com/dotnet/Announcements) will contain this bulletin as an issue and will include a link to a discussion issue. You can ask questions in the linked discussion issue.\n\n### Disclaimer\n\nThe information provided in this advisory is provided \"as is\" without warranty of any kind.
