Microsoft.NETCore.Jit fixed: 2.0.6 
Upgrade Microsoft.NETCore.Jit to 2.0.6
Microsoft.NETCore.Jit fixed: 1.1.7 
Upgrade Microsoft.NETCore.Jit to 1.1.7
Microsoft.NETCore.Jit fixed: 1.0.12 
Upgrade Microsoft.NETCore.Jit to 1.0.12
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for Microsoft.NETCore.Jit

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-0875, inspect your project dependencies for Microsoft.NETCore.Jit:

inspect dependencies for Microsoft.NETCore.Jit

Analyze the terminal output to locate any version of Microsoft.NETCore.Jit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.
