CRITICAL

Helm 2.0.0-2.15.1 - Symlink Following and Denial of Service via Malicious Chart

Title source: llm
STIX 2.1

Description

In Helm 2.x before 2.15.2, commands that deal with loading a chart as a directory or packaging a chart provide an opportunity for a maliciously designed chart to include sensitive content such as /etc/passwd, or to execute a denial of service (DoS) via a special file such as /dev/urandom, via symlinks. No version of Tiller is known to be impacted. This is a client-only issue.
