CVE-2024-26147
SOURCE - githubSummary
A Helm contributor discovered uninitialized variable vulnerability when Helm parses index and plugin yaml files missing expected content.
Impact
When either an index.yaml
file or a plugins plugin.yaml
file were missing all metadata a panic would occur in Helm.
In the Helm SDK this is found when using the LoadIndexFile
or DownloadIndexFile
functions in the repo
package or the LoadDir
function in the plugin
package. For the Helm client this impacts functions around adding a repository and all Helm functions if a malicious plugin is added as Helm inspects all known plugins on each invocation.
Patches
This issue has been resolved in Helm v3.14.2.
Workarounds
If a malicious plugin has been added which is causing all Helm client commands to panic, the malicious plugin can be manually removed from the filesystem.
If using Helm SDK versions prior to 3.14.2, calls to affected functions can use recover
to catch the panic.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.
