## Impact

Employing the `--nosignature` option with the RPM Package Manager (`rpm`) in Dockerfiles presents a substantial security risk. This flag directs RPM to bypass package signature verification during installations.

Neglecting the package signature check opens the door for the potential installation of tampered or malicious packages. This can result in malicious software or vulnerable versions being incorporated into the container image, which could critically jeopardize the container's security and the overall integrity of the applications it houses.

## How to Fix

## \[source,go]

* RUN rpm -i --nosignature somepackage.rpm
* RUN rpm -i somepackage.rpm

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec2-docker-10.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
