CVE-2024-29893

The ArgoCD repo-server component is vulnerable to a denial of service attack, where it is possible to crash the repo server component through an out-of-memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD’s helm package does not limit the size or time while fetching the data. It fetches and creates a byte slice from the retrieved data in one go. If the registry is implemented to push data continuously, the repo server will keep allocating memory until it runs out.
