Source: open-build-service Followup-For: Bug #903797 I checked 2.7 branch on upstream git. There was a merge for fixing "Handle links properly when doing backend build operations". Do not seems upstream also applied CVE-2018-7689 fix for 2.7.4. https://github.com/openSUSE/open-build-service/commits/2.7
I probably the best way to check this is setup an OBS instence and following the exploit to do a test. And may also useful to test if we have to backport the patch from 2.9 to 2.7.4. Best regards, -Andrew
