Re: [Buildroot] CVE-2022-30550 version range fix

Hello,

I'm still not clear what are CVE inquiries vs. CPE inquiries. My
inquiry here was regarding a CVE, so to me it made sense to report it
to you as the way to fix the issue was to fix a CVE report.

Could you clarify so that I can address any future report to the
correct entity?

Thanks a lot for your support!

Thomas

Hello Benjamin,

Thanks for the feedback, much appreciated, and thanks for taking into account the feedback. At the end of your e-mail, you said "For CPE related inquiries we request that you send them to cpe_dictionary@nist.gov", does that mean that some of my requests should have been sent to cpe_dictionary@nist.gov instead, and if so which ones?

Perhaps you are referring to my request:

        Subject: Numerous issues in CVEs for the "sox" project

 ?

Could you clarify, so that I can make sure I send my requests to the right contact?

Thanks a lot this effort on maintaining the NVD!

Best regards,

Thomas

Subject: CVE-2022-30550 version range fix

Hello,

CVE-2022-30550 is documented in your database as affecting versions of dovecot up to 2.3.20.

However, according to
https://dovecot.org/pipermail/dovecot-news/2022-July/000477.html, the fix for this issue is:

  https://github.com/dovecot/core/compare/7bad6a24%5E..a1022072.patch

And this commit is only in Dovecot 2.4.0, which means that versions 2.3.21, 2.3.21.1 are affected.

Here is some additional evidence based on the Git repository of Dovecot:

$ git log --format=oneline 2.3.21  | grep "auth: Fix handling passdbs with identical driver/args but"
$

So 2.3.21 doesn't have the fix.

$ git log --format=oneline 2.3.21.1  | grep "auth: Fix handling passdbs with identical driver/args but"
$

So 2.3.21.1 doesn't have the fix.

$ git log --format=oneline 2.4.0  | grep "auth: Fix handling passdbs with identical driver/args but"
7bad6a24160e34bce8f10e73dbbf9e5fbbcd1904 auth: Fix handling passdbs
with identical driver/args but different mechanisms/username_filter

Which means that 2.4.0 has the fix.

Therefore, your entry for CVE-2022-30550 should be fixed to indicate that versions up to (excluding) 2.4.0 are affected.

Thanks for your great work on maintaining this database! It would be create to have a public issue tracker to report issues.
