Issues found in build: helm-s3 v0.14.0

CVE-2022-41717

CVE Description

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped; an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.

CVE-2022-23524

CVE Description

Helm is a tool for managing Charts; pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to Uncontrolled Resource Consumption; resulting in Denial of Service. Input to functions in the strvals package can cause a stack overflow. In Go; a stack overflow cannot be recovered from. Applications that use functions from the strvals package in the Helm SDK can have a Denial of Service attack when they use this package and it panics. This issue has been patched in 3.10.3. SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the strvals functions.

CVE-2022-23525

CVE 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.

CVE-2022-23526

CVE 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_chartutil_ package that can cause a segmentation violation. The chartutil package contains a parser that loads a JSON Schema validation file. For example; the Helm client when rendering a chart will validate its values with the schema file. The chartutil package parses the schema file and loads it into structures Go can work with. Some schema files can cause array data structures to be created causing a memory violation. Applications that use the chartutil package in the Helm SDK to parse a schema file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. 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 schema files that are correctly formatted before passing them to the chartutil functions.
