Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Trivy versions before 0.71.0 are vulnerable. When scanning a Helm chart archive, the tar unpacker reads each entry without a size limit, so a small crafted .tgz file can expand to gigabytes and exhaust host memory. An attacker needs to place such a file where Trivy scans it as a Helm chart, which can happen via a contributed pull request or untrusted build context, and the result is denial of service. Upgrade to Trivy 0.71.0 or later; until then, set a memory limit on the Trivy process and exclude untrusted chart archives from scans.
