It is reliably triggered after GC when code is structured in a particular way. There is no known general exploit that could be used as a denial of service attack.\n\n## Affected packages\n\n- `sqlite3-ruby <= 2.9.4`\n- `sqlite3 <= 2.9.4`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `sqlite3-ruby 2.9.5`\n- `sqlite3 2.9.5`","depth":"sunlit","depthScore":14,"depthScoreParts":{"impact":13.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
