HIGH

ollama < 0.1.34 - Denial of Service via /dev/random Path Handling

Title source: llm
STIX 2.1

Description

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).
