CVE-2024-39721

7.5 highEPSS 2.7%

High (7.5) in ollama ollama. EPSS 2.7% chance of exploitation in the next 30 days.

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).
