Denial of service through through repository index file
CVE: CVE-2022-23525
Component: helm
CWE: CWE-476
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-12-15T00:00:00+00:00

A flaw was found in Helm. Applications that use the _repo_ package in Helm SDK to parse an index file may suffer a denial of service when that input causes a panic that cannot be recovered from. The Helm Client will panic with an index file that causes a memory violation panic.

Statement: Red Hat has rated this a Moderate impact as Helm is a user utility, which when ran locally, interacts with the kubernetes API. As such, a panic in the Helm client does not constitute an availability impact to the rest of the system(s).
