NVD description
An issue was discovered in Ollama before 0.1.34. The CreateModelHandler function uses os.Open to read a file until completion. The req.Path parameter is user-controlled and can be set to /dev/random, which is blocking, causing the goroutine to run infinitely (even after the HTTP request is aborted by the client).
What to do
- Upgrade Ollama to
0.1.34or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
