    CVE-2017-18367

    Published: 24 Apr 2019Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
