CVE-2017-18367 (opens in a new tab)How to fix?
Upgrade RHEL:7 atomic-openshift to version 0:3.11.232-1.git.0.a5bc32f.el7 or higher.
This issue was patched in RHSA-2020:2479.
NVD Description
Note: Versions mentioned in the description apply only to the upstream atomic-openshift package and not the atomic-openshift 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.
