Ollama Vulnerable to Denial of Service (DoS) via Crafted GZIP
High7.5CVE-2024-12886 · Published Mar 20, 2025 · updated Mar 31, 2025
An Out-Of-Memory (OOM) vulnerability exists in the `ollama` server version 0.3.14. This vulnerability can be triggered when a malicious API server responds with a gzip bomb HTTP response, leading to the `ollama` server crashing. The vulnerability is present in the `makeRequestWithRetry` and `getAuthorizationToken` functions, which use `io.ReadAll` to read the response body. This can result in excessive memory usage and a Denial of Service (DoS) condition.
