## 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: | Command | Condition | | --- | --- | | `trivy config ` | Directory contains a crafted `.tgz` Helm chart (misconfiguration scanning is always enabled) | | `trivy filesystem --scanners misconf ` | Directory contains a crafted `.tgz` Helm chart **and** `--scanners misconf` is explicitly enabled | | `trivy image --scanners misconf ` | 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 `

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
