Ollama < 0.1.34 DoS

high Nessus Plugin ID 210501

Language:

Synopsis

The Ollama instance installed on the remote host is affected by a denial of service vulnerability.

Description

The version of Ollama installed on the remote host is prior to 0.1.34. It is, therefore, affected by a denial-of-service vulnerability:

 - 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).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Ollama version 0.1.34 or later.
