CVE-2017-9269

In libzypp before August 2018 GPG keys attached to YUM repositories were not correctly pinned, allowing malicious repository mirrors to silently downgrade to unsigned repositories with potential malicious content.

These are all security issues fixed in the libzypp-17.28.4-1.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the zypper-1.14.49-1.2 package on the GA media of openSUSE Tumbleweed.
