How to fix the issue

To update the Microsoft.Bcl.Memory NuGet package, apply one of the following methods:

NuGet Package Manager UI in Visual Studio: - Open the project in Visual Studio. - Right-click on the project in Solution Explorer and select "Manage NuGet Packages..." or navigate to "Project > Manage NuGet Packages". - In the NuGet Package Manager window, select the "Updates" tab. This tab lists packages with available updates from the configured package sources. - Select the package(s) to update. A specific version can be chosen from the dropdown, or the latest available version can be selected. - Click the "Update" button.

Using the NuGet Package Manager Console in Visual Studio: - Open the project in Visual Studio. - Navigate to "Tools > NuGet Package Manager > Package Manager Console". - To update a specific package to its latest version, run the following Update-Package command:

Update-Package -Id Microsoft.Bcl.Memory

Using the .NET CLI (Command Line Interface): - Open a terminal or command prompt in the project's directory. - To update a specific package to its latest version, run the following command:

dotnet package update Microsoft.Bcl.Memory

Once the NuGet package reference has been updated, the application must be recompiled and redeployed. Additionally, it is recommended to update the runtime and/or SDKs, but unless the application targets .NET 9 or higher, updating the runtime and/or SDK is not a required step to patch this vulnerability.

Visual Studio:\n- Open the project in Visual Studio.\n- Right-click on the project in Solution Explorer and select \"Manage NuGet Packages...\" or navigate to \"Project \u003e Manage NuGet Packages\".\n- In the NuGet Package Manager window, select the \"Updates\" tab. This tab lists packages with available updates from the configured package sources.\n- Select the package(s) to update. A specific version can be chosen from the dropdown, or the latest available version can be selected.\n- Click the \"Update\" button.\n\nUsing the NuGet Package Manager Console in Visual Studio:\n- Open the project in Visual Studio.\n- Navigate to \"Tools \u003e NuGet Package Manager \u003e Package Manager Console\".\n- To update a specific package to its latest version, run the following Update-Package command:\n\n```\nUpdate-Package -Id Microsoft.Bcl.Memory\n```\n\nUsing the .NET CLI (Command Line Interface):\n- Open a terminal or command prompt in the project\u0027s directory.\n- To update a specific package to its latest version, run the following command:\n\n```\ndotnet package update Microsoft.Bcl.Memory\n```\n\nOnce the NuGet package reference has been updated, the application must be recompiled and redeployed. Additionally, it is recommended to update the runtime and/or SDKs, but unless the application targets .NET 9 or higher, updating the runtime and/or SDK is not a required step to patch this vulnerability.\n\n## Other Information\n\n### Reporting Security Issues\n\nIf a potential security issue has been found in a supported version of .NET, it should be reported 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\nQuestions about this issue can be asked 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. Questions can be asked in the linked discussion issue.\n\n### Disclaimer\n\nThe information provided in this advisory is provided \"as is\" without warranty of any kind.

Details

An issue was discovered in BusyBox before 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes.

Vulnerability from github – Published: 2022-05-14 01:20 – Updated: 2022-05-14 01:20
VLAI
Details

In tinysvcmdns through 2018-01-16, an mDNS server processing a crafted packet can perform arbitrary data read operations up to 16383 bytes from the start of the buffer. This can lead to a segmentation fault in uncompress_nlabel in mdns.c and a crash of the server (depending on the memory protection of the CPU and the operating system), or disclosure of memory content via error messages or a server response. NOTE: the product's web site states "This project is un-maintained, and has been since 2013. ... There are known vulnerabilities ... You are advised to NOT use this library for any new projects / products."

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design

Strategy: Language Selection

Use a language that provides appropriate memory abstractions.

CAPEC-540: Overread Buffers

An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
