This is an embargoed bug. This means that this information is not public. Please do NOT: - talk to other people about this unless they're involved in fixing the issue - make this bug public - submit this into OBS (e.g. fix Leap/Tumbleweed) until this bug becomes public (e.g. no EMBARGOED tag on the header) Consult with security team if you think that the issue is public and the bug is still private (e.g. subject still contains "EMBARGOED"). Please do NOT make the bug public yourself! Please be aware that the SUSE:SLE-15-SP4:GA codestream is available via OBS, so do NOT submit there before this is public. These are the steps that are asked from you: 1, Your primary responsibility is to submit a fix for this issue. Here's a how-to for submitting packages for maintenance releases in IBS: https://confluence.suse.com/display/maintenance/How+to+Submit+Packages+or+Containers+to+Maintenance Apart from the GA codestreams mentioned above, you can submit to IBS anytime. This is private and allows us to start testing as soon as possible. 2, We also want to fix openSUSE if it's affected. $ is_maintained $PACKAGE will tell you if the package is inherited from SLES or if it is branched for openSUSE. There are two cases: - It's coming from SLES: The update will automatically be released for openSUSE. Nothing to do for you. - It's branched for openSUSE: You need to submit AFTER the bug became public, to the current openSUSE codestreams. For openSUSE Factory please submit to the devel project of your package AFTER the bug became public. Security will then take the following steps: - We wait for your submission and package them into an incident for QA testing. The QA tester might reach out to you if they find issues with the update. - Once the coordinated release date (CRD), the date this issue should become public, is reached (or for internal findings: once we're done testing), we remove the EMBARGOED tag from this bug and publish the updates. - Only if the bug here is public you may submit to public repositories (OBS). You can contact us at: * IRC: irc.suse.de #security * Do NOT use Slack or any non-SUSE hosted messaging services * Email: security-team@suse.de
