What is CVE-2024-39721?

A denial of service vulnerability exists in Ollama software versions before 0.1.34 due to improper handling of user-controlled file paths in the CreateModelHandler function. An attacker can manipulate the req.Path parameter to point to /dev/random, which causes blocking behavior. This leads to a goroutine running infinitely, even if the client aborts the HTTP request. Such behavior can degrade the performance of the service, making it unresponsive to legitimate requests.
