CVE-2022-23525— Helm vulnerable to Denial of service via NULL Pointer Dereference

Quick assessment

Affected

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Helm是一款Kubernetes包管理器。 Helm 3.10.3之前版本存在安全漏洞，该漏洞源于受 _repo_package 中的空指针取消引用的约束，_repo_ 包解析存储库的索引文件并将其加载到 Go 可以使用的结构中，某些索引文件可能会导致创建数组数据结构，从而导致内存冲突。

Vulnerability Title
Helm vulnerable to Denial of service via NULL Pointer Dereference
Source: CVE Program / CVE List V5
Vulnerability Description
Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to NULL Pointer Dereference in the _repo_package. The _repo_ package contains a handler that processes the index file of a repository. For example, the Helm client adds references to chart repositories where charts are managed. The _repo_ package parses the index file of the repository and loads it into structures Go can work with. Some index files can cause array data structures to be created causing a memory violation. Applications that use the _repo_ package in the Helm SDK to parse an index file can 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. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been patched in 3.10.3. SDK users can validate index files that are correctly formatted before passing them to the _repo_ functions.
