CVE-2017-18367

HIGH

libseccomp-golang < 0.9.0 - Improper Input Validation in BPF Generation

Title source: llm
STIX 2.1

Description

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.
