Description

Summary

When Trivy scans a Helm chart archive (.tgz), its custom tar unpacker reads each entry with io.ReadAll(tr) and no size limit. An attacker who can place a malicious .tgz file in the scanned path can craft a small compressed archive that decompresses to gigabytes, causing the Trivy process to be killed by the OS OOM killer.

Affected configurations

Exploitation requires the attacker to place a crafted .tgz file in a location that Trivy will scan as a Helm chart. This applies to the following scan targets:

CommandCondition
trivy config <dir>Directory contains a crafted .tgz Helm chart (misconfiguration scanning is always enabled)
trivy filesystem --scanners misconf <dir>Directory contains a crafted .tgz Helm chart and --scanners misconf is explicitly enabled
trivy image --scanners misconf <image>Image contains a crafted .tgz Helm chart and --scanners misconf is explicitly enabled

Realistic scenarios include:

  • A CI pipeline that runs trivy config . on a repository where a contributor can submit a pull request containing a crafted chart archive.
  • A pipeline that scans a container image with --scanners misconf, whose build context includes untrusted .tgz files.

Impact

An attacker who satisfies the conditions above can exhaust all available memory on the host running Trivy. The OS OOM killer will terminate the Trivy process and may affect other processes sharing the same host or CI runner.

The practical impact in CI environments is denial of service: the scan fails, the pipeline is blocked, and repeated submissions re-trigger the same condition. Cloud CI runners may also incur additional costs for consumed resources.

There is no impact on confidentiality or integrity of the scanned system.

Patches

Fixed in Trivy v0.71.0 (#10718). The custom tar unpacker was replaced with archive.LoadArchiveFiles from the official helm.sh/helm/v4 SDK, which enforces per-entry and total size limits and validates archive structure. Users should upgrade to v0.71.0 or later.

Workarounds

If upgrading is not immediately possible:

  • Set a memory limit (cgroup/container) on the Trivy process to bound the blast radius.
  • Use --skip-dirs to exclude directories containing untrusted Helm chart archives from the scan.
  • Avoid scanning repositories or images with untrusted .tgz files.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/aquasecurity/trivy. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/aquasecurity/trivy to 0.71.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q3fv-x8vg-qqm4 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-q3fv-x8vg-qqm4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-q3fv-x8vg-qqm4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
