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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
