Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incorretly generated Berkeley Packet Filters (BPF) evaluated multiple syscall argument rules using OR instead of AND logic, allowing attackers to bypass restricted syscall parameters. This vulnerability is tracked under CVE-2017-18367.
Auth Bypass: Failing to enforce thread synchronization (TSync) attributes unconditionally allowed newly spawned Go application threads or goroutines to execute outside the protection of initialized seccomp filters.
Sandbox Escape: Lack of strict validation on user-supplied comparison operators allowed invalid filter rules to bypass boundaries during filter construction.
