CVE-2019-18658: Helm

Critical severity, CVSS 9.8. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products

• Helm Helm: from 2.0.0, before 2.15.2 (fixed in 2.15.2)
