CSIRTS triage
- What
- Multiple vulnerabilities enable a local attacker to perform a denial of service attack.
- Who is affected
- Local users on systems running CUPS print service.
- Urgency
- Medium severity limited to local attacks; denial of service impact disrupts printing but not data security.
