FKIE_CVE-2024-12055

Vulnerability from fkie_nvd - Published: 2025-03-20 10:15 - Updated: 2025-05-13 13:28
Summary
A vulnerability in Ollama versions <=0.3.14 allows a malicious user to create a customized gguf model file that can be uploaded to the public Ollama server. When the server processes this malicious model, it crashes, leading to a Denial of Service (DoS) attack. The root cause of the issue is an out-of-bounds read in the gguf.go file.
