Malicious Ollama models pose risks via disk, VRAM, and prompt manipulation

A malicious model downloaded through Ollama poses risks beyond traditional viruses, primarily through untrusted input to its C parser and filesystem access. Potential damages include disk exhaustion, VRAM starvation, corrupted model files, and the ability for a malicious model to rewrite user prompts by manipulating its system template. To mitigate these threats, users are advised to bind the Ollama daemon to localhost, pin models by their SHA256 digest, and run containers as non-root users with read-only filesystems and capped model volumes.
