CVE-2017-18367

CVE-2017-18367 affects libseccomp-golang 0.9.0 and earlier. The root cause is that the BPFs generated by libseccomp-golang OR multiple syscall-argument checks instead of ANDing them, enabling a process under a restrictive seccomp filter that specifies multiple arguments to bypass the intended acc...
