CVE-2024-39720GHSA-95j2-w8x7-hm88

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/ollama/ollama 0.1.46), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

An issue was discovered in Ollama before 0.1.46. An attacker can use two HTTP requests to upload a malformed GGUF file containing just 4 bytes starting with the GGUF custom magic header. By leveraging a custom Modelfile that includes a FROM statement pointing to the attacker-controlled blob file, the attacker can crash the application through the CreateModel route, leading to a segmentation fault (signal SIGSEGV: segmentation violation).

# Patch Next advisory brief: CVE-2024-39720

Advisory: Ollama Out-of-bounds Read
IDs: CVE-2024-39720, GHSA-95j2-w8x7-hm88
Record: https://patchnext.com/advisories/cve-2024-39720 (revision 1, source checked 26 Oct 2026, 15:08 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/ollama/ollama 0.1.46. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/ollama/ollama: affected < 0.1.46; fixed in 0.1.46

## Suggested inspection (read-only)
- Go github.com/ollama/ollama: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/ollama/ollama.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-95j2-w8x7-hm88 (GitHub-reviewed advisory GHSA-95j2-w8x7-hm88 lists affected ranges: Go github.com/ollama/ollama >=0 <0.1.46)

Commands are suggestions: review each one before running it.
