Title
Unbounded allocation when parsing GNU sparse map in archive/tar
Summary
tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations.

Title
Excessive resource consumption when printing error string for host certificate validation in crypto/x509
Summary
Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.

Summary
Helm vulnerable to denial of service through through repository index file
Details
Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the _repo_ package that can cause a segmentation violation. Applications that use functions from the _repo_ package in the Helm SDK can have a Denial of Service attack when they use this package and it panics.
Impact
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.
Patches
This issue has been resolved in 3.10.3.
Workarounds
SDK users can validate index files that are correctly formatted before passing them to the _repo_ functions.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm vulnerable to Code Injection through malicious chart.yaml content
Details
A Helm contributor discovered that a specially crafted Chart.yaml file along with a specially linked Chart.lock file can lead to local code execution when dependencies are updated.
Impact
Fields in a Chart.yaml file, that are carried over to a Chart.lock file when dependencies are updated and this file is written, can be crafted in a way that can cause execution if that same content were in a file that is executed (e.g., a bash.rc file or shell script). If the Chart.lock file is symlinked to one of these files updating dependencies will write the lock file content to the symlinked file. This can lead to unwanted execution. Helm warns of the symlinked file but did not stop execution due to symlinking.
This affects when dependencies are updated. When using the helm command this happens when helm dependency update is run. helm dependency build can write a lock file when one does not exist but this vector requires one to already exist. This affects the Helm SDK when the downloader Manager performs an update.
Patches
This issue has been resolved in Helm v3.18.4
Workarounds
Ensure the Chart.lock file in a chart is not a symlink prior to updating dependencies.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Gin Web Framework does not properly sanitize filename parameter of Context.FileAttachment function
Details
The filename parameter of the Context.FileAttachment function is not properly sanitized. A maliciously crafted filename can cause the Content-Disposition header to be sent with an unexpected filename value or otherwise modify the Content-Disposition header. For example, a filename of "setup.bat";x=.txt" will be sent as a file named "setup.bat".
If the FileAttachment function is called with names provided by an untrusted source, this may permit an attacker to cause a file to be served with a name different than provided. Maliciously crafted attachment file name can modify the Content-Disposition header.

Summary
Helm Allows A Specially Crafted JSON Schema To Cause A Stack Overflow
Details
A Helm contributor discovered that a specially crafted JSON Schema within a chart can lead to a stack overflow.
Impact
A JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow.
Patches
This issue has been resolved in Helm v3.17.3.
Workarounds
Ensure that the JSON Schema within any charts loaded by Helm does not have a large number of nested references. These JSON Schema files are larger than 10 MiB.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm's Missing YAML Content Leads To Panic
Details
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.

Summary
Helm Vulnerable to denial of service through string value parsing
Details
Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the _strvals_ package that can cause an out of memory panic. Out of memory panics 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.
Impact
The _strvals_ package contains a parser that turns strings into Go structures. For example, the Helm client has command line flags like --set, --set-string, and others that enable the user to pass in strings that are merged into the values. The _strvals_ package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing an out of memory panic.
Applications that use the _strvals_ package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from.
The Helm Client will panic with input to --set, --set-string, and other value setting flags that causes an out of memory panic. Helm is not a long running service so the panic will not affect future uses of the Helm client.
Patches
This issue has been resolved in 3.9.4.
Workarounds
SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the _strvals_ functions.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm vulnerable to denial of service through schema file
Details
Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the _chartutil_ package that can cause a segmentation violation. Applications that use functions from the _chartutil_ package in the Helm SDK can have a Denial of Service attack when they use this package and it panics.
Impact
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.
The Helm Client will panic with a schema 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.
Patches
This issue has been resolved in 3.10.3.
Workarounds
SDK users can validate schema files that are correctly formatted before passing them to the _chartutil_ functions.

Helm's security policy is spelled out in detail in our SECURITY document.

Summary
jwt-go allows excessive memory allocation during header parsing
Details
Summary
Function parse.ParseUnverified currently splits (via a call to strings.Split) its argument (which is untrusted data) on periods.
As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. Relevant weakness: CWE-405: Asymmetric Resource Consumption (Amplification)

Summary
Helm May Panic Due To Incorrect YAML Content
Details
A Helm contributor discovered an improper validation of type error when parsing Chart.yaml and index.yaml files that can lead to a panic.
Impact
There are two areas of YAML validation that were impacted. First, when a Chart.yaml file had a null maintainer or the child or parent of a dependencies import-values could be parsed as something other than a string, helm lint would panic. Second, when an index.yaml had an empty entry in the list of chart versions Helm would panic on interactions with that repository.
Patches
This issue has been resolved in Helm v3.18.5.
Workarounds
Ensure YAML files are formatted as Helm expects prior to processing them with Helm.
References
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm vulnerable to information disclosure via getHostByName Function
Details
A Helm contributor discovered an information disclosure vulnerability using the getHostByName template function.
Impact
getHostByName is a Helm template function introduced in Helm v3. The function is able to accept a hostname and return an IP address for that hostname. To get the IP address the function performs a DNS lookup. The DNS lookup happens when used with helm install|upgrade|template or when the Helm SDK is used to render a chart.
Information passed into the chart can be disclosed to the DNS servers used to lookup the IP address. For example, a malicious chart could inject getHostByName into a chart in order to disclose values to a malicious DNS server.
Patches
The issue has been fixed in Helm 3.11.1.
Workarounds
Prior to using a chart with Helm verify the getHostByName function is not being used in a template to disclose any information you do not want passed to DNS servers.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm vulnerable to denial of service through string value parsing
Details
Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the strvals package that 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.
Impact
The strvals package contains a parser that turns strings into Go structures. For example, the Helm client has command line flags like --set, --set-string, and others that enable the user to pass in strings that are merged into the values. The strvals package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing a stack overflow.
Applications that use the strvals package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from.
The Helm Client will panic with input to --set, --set-string, and other value setting flags that causes a stack overflow. Helm is not a long running service so the panic will not affect future uses of the Helm client.
Patches
This issue has been resolved in 3.10.3.
Workarounds
SDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the strvals functions.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Summary
Helm dependency management path traversal
Details
A Helm contributor discovered a path traversal vulnerability when Helm saves a chart including at download time.
Impact
When either the Helm client or SDK is used to save a chart whose name within the Chart.yaml file includes a relative path change, the chart would be saved outside its expected directory based on the changes in the relative path. The validation and linting did not detect the path changes in the name.
Patches
This issue has been resolved in Helm v3.14.1.
Workarounds
Check all charts used by Helm for path changes in their name as found in the Chart.yaml file. This includes dependencies.

Summary
Improper input validation in github.com/gin-gonic/gin
Details
Versions of the package github.com/gin-gonic/gin before version 1.9.0 are vulnerable to Improper Input Validation by allowing an attacker to use a specially crafted request via the X-Forwarded-Prefix header, potentially leading to cache poisoning.
Note: Although this issue does not pose a significant threat on its own it can serve as an input vector for other more impactful vulnerabilities. However, successful exploitation may depend on the server configuration and whether the header is used in the application logic.

Summary
Helm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion
Details
A Helm contributor discovered that it was possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination.
Impact
A malicious chart can point $ref in values.schema.json to a device (e.g. /dev/*) or other problem file which could cause Helm to use all available memory and have an out of memory (OOM) termination.
Patches
This issue has been resolved in Helm v3.18.5.
Workarounds
Make sure that all Helm charts that are being loaded into Helm doesn't have any reference of $ref pointing to /dev/zero.

Summary
Helm Allows A Specially Crafted Chart Archive To Cause Out Of Memory Termination
Details
A Helm contributor discovered that a specially crafted chart archive file can cause Helm to use all available memory and have an out of memory (OOM) termination.
Impact
A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate.
Patches
This issue has been resolved in Helm v3.17.3.
Workarounds
Ensure that any chart archive files being loaded by Helm do not contain files that are large enough to cause the Helm Client or SDK to use up available memory leading to a termination.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.
