github.com/ollama/ollama fixed: 0.1.29 
Upgrade github.com/ollama/ollama to 0.1.29
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 github.com/ollama/ollama

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-28224, inspect your project dependencies for Github.com/ollama/ollama:

inspect dependencies for github.com/ollama/ollama

Analyze the terminal output to locate any version of Github.com/ollama/ollama in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.29), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action, where the product performs reverse dns resolution on an ip address to obtain the hostname and make a security decision, but it does not properly ensure that the ip address is truly associated with the hostname. In Github.com/ollama/ollama, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Ollama before 0.1.29 has a DNS rebinding vulnerability that can inadvertently allow remote access to the full API, thereby letting an unauthorized user chat with a large language model, delete a model, or cause a denial of service (resource exhaustion).
