Hi,

The following vulnerability was published for golang-github-seccomp-libseccomp-golang.

CVE-2017-18367[0]:
| 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.
