Hi Team,

Our scanning tools ( blackduck ) are reporting base image vulnerabilities for the OPAL version 7.2.2 (we found 7 critical and 7 high ), these issues are not related to OPAL source code. Please address these issue as soon as possible to make OPAL as vulnerability free.

Example :
debian: libzstd1/1.4.8+dfsg-2.1/amd64 - BDSA-2019-5223
Zstandard command-line utility is vulnerable to information disclosure via improper default permissions on output files. Correct file permissions are only set at completion time which could allow a local attacker to read or write to a file during compression or decompression.

Note: The initial fix for this vulnerability was incomplete and a further fix was required. This was disclosed as CVE-2021-24032(BDSA-2021-2294).

Hi @rgidda, thanks for reporting!
Do you know if your tool takes into consideration only the base image or the other attributes of the image?
For example, if the base image has a package with vulnerability but we uninstall it in the next step, will it be able to detect it?
Another question is whether this tool is free to use if we want to check it ourselves?

And last one, do you have a recommended base image that you use, it would be great if you want to help us with this and contribute to Open Source 🥇

Hi @obsd , We are using blackduck enterprise edition , it will scan all attributes of the image including base images. Please upgrade you base images to latest versions and replace/update the packages which got critical vulnerabilities.

You can use below scanning tool locally.

hi @obsd

I have made an attempt at this. All debian vulnerabilities are resolved in these changes, however there seems to be an issue with OPA running. In this commit there are docker compose logs to see this sort of log running every couple of seconds:

opal_client.engine.runner �[0m|�[1m INFO | Running policy engine inline: opa run --server --addr=:8181 --authentication=off --authorization=off --log-level=info�[0m
opal_client.engine.runner �[0m|�[1m INFO | Running policy engine rehydration callbacks�[0m

devine12@f1cbc2b

any advice on how to debug?

Hi @devine12
Thanks for sharing it with us.
I think that what happens is that our watchdog can't identify OPA running so it tries to run it again.
Can you set the log level to debug it may help us understand this better, anyway, I will ask someone from the team to take a look.

Hi @devine12 , there can be many reasons why OPA restarts in alpine linux.

We did use alpine before for OPAL and moved away towards the official python docker image due to build-time issues, stability issues and DNS issues.

It does look like they finally fixed it in alpine 3.18 - we'll have to check.

@obsd for now i suggest sticking with the least vulnerable official python base image and patch it accordingly until we can field-test alpine stability.

Hi @asafc and @obsd, thanks for the reply -

The restarting was fixed by switching asyncio.wait -> asyncio.gather in the opa engine

see 68f1e6a

Due to the security gates set in our ci pipelines - we cannot have any critical vuln >9 cvss.

Cool @devine12, is it working now with the new image?
If you can test it we will be glad to get this code contribution from you
Also, have someone from Permit that will guide you on how to make it ready to merge into the main project

Hi @obsd -

Yes it is working now.

For local test I made separate branch (devine12@17e0518) with:

  1. docker-compose-alpine-test.yml to run with locally built images
  2. Script to build client and server alpine images locally then spin up docker-compose-alpine-test with these images
  3. Logs of the above script running

I have raised PR (https://github.com/permitio/opal/pull/534/files) and reached out in slack - any other guidance on how to move forward

Hi @devine12 , thank you very much, your PR is much appreciated!
I will talk with this feature owner and ask him to review this in his next OSS window, once we merge it I will let you know.
Can you send me a private message in our community Slack (It's Oded BD) so I can update you there?
