Dear Ubuntu Community,

I have a question regarding CVE-2021-41617 , On https://ubuntu.com/security/CVE-2021-41617 I can see that a fix for Ubuntu Jammy is needed , but in the changelog https://launchpad.net/ubuntu/jammy/+source/openssh/+changelog I can see that CVE-2021-41617 is fixed. Also the security scanners found Ubuntu Jammy vulnerable to the mentioned CVE. Do anyone know why it is still reported for Jammy am I missing something?

Thanks in advance

    It seems someone forgot to update the Ubuntu security site, as it seems fixed. I'd trust the changenotes more than the CVE site in this case. May 31, 2023 at 11:37

    "security scanners" are notoriously ill-informed and prone to false results. Their output should be considered a first draft for human review.

The available evidence leads to the conclusion that the CVE mitigation patch was indeed applied in 2021, and that the discrepancy has a reasonable explanation.

The patch was seemingly applied at Debian, not by the Ubuntu Security Team. The reference bug number "(closes: #995130)" is a Debian bug reference, not a Launchpad bug.

Nothing wrong there -- that's a reasonable place to do the patching, and the patching was done by a developer with plenty of experience with that code and a great reputation at both Debian and Ubuntu. But it does perhaps explain why the Ubuntu tracker didn't notice.

I have pinged the Ubuntu Security Team to review and decide if any change to their tracker is needed.

  • thank you very much for the quick resolution. I'd like to ask about this one ubuntu.com/security/CVE-2020-14145 , here only versions of openssh up to 8.6 are mentioned. In Jammy we have openssh 8.9 do this mean that it is not vulnerable to the mentioned CVE ? May 31, 2023 at 13:08
  • Please open new Questions for separate issues. Be sure to read the engineer comments, which usually explain the issue (and resolution) better than the volunteers here can.
