Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9811 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-03-06 00:31 – Updated: 2025-03-06 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

block: disable the elevator int del_gendisk

The elevator is only used for file system requests, which are stopped in del_gendisk. Move disabling the elevator and freeing the scheduler tags to the end of del_gendisk instead of doing that work in disk_release and blk_cleanup_queue to avoid a use after free on q->tag_set from disk_release as the tag_set might not be alive at that point.

Move the blk_qos_exit call as well, as it just depends on the elevator exit and would be the only reason to keep the not exactly cheap queue freeze in disk_release.

Executive summary

Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 7.0 and .NET 6.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.

A vulnerability exists in how .NET reads debugging symbols, where reading a malicious symbols file may result in remote code execution.

Discussion

Discussion for this issue can be found at https://github.com/dotnet/runtime/issues/82112

Mitigation factors

Microsoft has not identified any mitigating factors for this vulnerability.

Affected software

  • Any .NET 7.0 application running on .NET 7.0.2 or earlier.
  • Any .NET 6.0 application running on .NET 6.0.13 or earlier.

If your application uses the following package versions, ensure you update to the latest version of .NET.

.NET 7

Package name Affected version Patched version
Microsoft.NetCore.App.Runtime.win-arm >= 7.0.0, <= 7.0.2 7.0.3
Microsoft.NetCore.App.Runtime.win-arm64 >= 7.0.0, <= 7.0.2 7.0.3
Microsoft.NetCore.App.Runtime.win-x64 >= 7.0.0, <= 7.0.2 7.0.3

Advisory FAQ

How do I know if I am affected?

If you have a runtime or SDK with a version listed, or an affected package listed in affected software, you're exposed to the vulnerability.

How do I fix the issue?

  • To fix the issue please install the latest version of .NET 6.0 or .NET 7.0. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs.
  • If you have .NET Core 3.1 or greater installed, you can list the versions you have installed by running the dotnet --info command. You will see output like the following;
  • If you are using one of the affected packages, please update to the patched version listed above.
.NET Core SDK (reflecting any global.json):

 Version:   6.0.300
 Commit:    8473146e7d

Runtime Environment:

 OS Name:     Windows
 OS Version:  10.0.18363
 OS Platform: Windows
 RID:         win10-x64
 Base Path:   C:\Program Files\dotnet\sdk\6.0.300\

Host (useful for support):

  Version: 6.0.5
  Commit:  8473146e7d

.NET Core SDKs installed:

  6.0.300 [C:\Program Files\dotnet\sdk]

.NET Core runtimes installed:

  Microsoft.AspNetCore.App 6.0.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 6.0.5 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  Microsoft.WindowsDesktop.App 6.0.5 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download
  • If you're using .NET 7.0, you should download and install Runtime 7.0.3 or SDK 7.0.103 (for Visual Studio 2022 v17.4) from https://dotnet.microsoft.com/download/dotnet-core/7.0.
  • If you're using .NET 6.0, you should download and install Runtime 6.0.14 or SDK 6.0.114 (for Visual Studio 2022 v17.1) from https://dotnet.microsoft.com/download/dotnet-core/6.0.

.NET 6.0 and and .NET 7.0 updates are also available from Microsoft Update. To access this either type "Check for updates" in your Windows search, or open Settings, choose Update & Security and then click Check for Updates.

Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.

Additionally, if you've deployed self-contained applications targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.

Other Information

Reporting Security Issues

If you have found a potential security issue in .NET 6.0 or .NET 7.0, please email details to secure@microsoft.com. Reports may qualify for the Microsoft .NET Core & .NET 5 Bounty. Details of the Microsoft .NET Bounty Program including terms and conditions are at https://aka.ms/corebounty.

Details

Foxit PDF Reader Annotation Use-After-Free Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of Annotation objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-21083.

Strategy: Attack Surface Reduction

When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

No CAPEC attack patterns related to this CWE.
