CVE-2017-18367 (opens in a new tab)How to fix?
Upgrade RHEL:7 openshift-clients to version 0:4.1.27-201912021146.git.0.a40116f.el7 or higher.
This issue was patched in RHSA-2019:4087.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openshift-clients package and not the openshift-clients package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument.
