Description Karol Babioch 2018-05-22 09:54:31 UTC

Kubernetes CRI-O version prior to 1.9 contains a Privilege Context Switching
Error (CWE-270) vulnerability in the handling of ambient capabilities that can
result in containers running with elevated privileges, allowing users abilities
they should not have. This attack appears to be exploitable via container
execution. This vulnerability appears to have been fixed in 1.9.

Comment 1 Valentin Rothberg 2018-05-22 10:00:48 UTC
We are only offering CRI-O for Tumbleweed and Kubic, both in version 1.9 (and soon 1.10), so the CVE doesn't seem to affect us. In case I am missing something, feel free to re-open the bug.

Thanks a lot for reporting the bug!
Comment 4 Karol Babioch 2018-05-22 10:21:40 UTC
You are right, of course. I'm sorry I somehow misread the message and believed that 1.9 would be affected, too.
