Descriptions

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.

libseccomp-golang versión 0.9.0 y anteriores, BPF generan incorrectamente múltiples argumentos OR en lugar de ANDing. Un proceso que se realiza bajo un filtro seccomp restrictivo que especificó múltiples argumentos de syscall podría omitir las restricciones de acceso previstas al especificar un único argumento coincidente.

It was discovered that libseccomp-golang did not properly generate BPFs. If a process were running under a restrictive seccomp filter that specified multiple syscall arguments, the application could potentially bypass the intended restrictions put in place by seccomp.
