Summary
A vulnerability in Ollama before version 0.1.46 allows an attacker to crash the application by uploading a malformed GGUF file (a model format file) using two HTTP requests and then referencing it in a custom Modelfile. This causes a segmentation fault (a type of crash where the program tries to access memory it shouldn't), making the application unavailable.
Solution / Mitigation
Update Ollama to version 0.1.46 or later.
