How to Fix CVE-2017-18367

To remediate this vulnerability, upgrade all affected Github.com/seccomp/libseccomp golang dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/seccomp/libseccomp-golang fixed: 0.9.1 
Upgrade github.com/seccomp/libseccomp-golang to 0.9.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/seccomp/libseccomp-golang

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-18367, inspect your project dependencies for Github.com/seccomp/libseccomp golang:

inspect dependencies for github.com/seccomp/libseccomp-golang

Analyze the terminal output to locate any version of Github.com/seccomp/libseccomp golang in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Github.com/seccomp/libseccomp golang, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
