Trivy: Helm chart tar bomb causes OOM via unbounded io.ReadAll in parser

Trivy is a security scanner. Prior to 0.71.0, 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. This vulnerability is fixed in 0.71.0.

Trivy: Path traversal via a crafted vulnerability database or other downloaded artifacts

Trivy is a security scanner. Prior to 0.71.1, when Trivy downloads an OCI artifact, it uses the org.opencontainers.image.title annotation from the artifact manifest as the destination filename without validation. An attacker who can make Trivy fetch an attacker-controlled artifact can supply a crafted annotation that resolves to a path outside the intended destination, causing Trivy to write the layer content to an arbitrary location on the host filesystem. This vulnerability is fixed in 0.71.1.
