description

JP1/Automatic Job Management System 3 Manager and Agent versions from 11-00 through versions before 13-50-31 are affected by a stack-based buffer overflow; Agent Minimal Edition is also listed as affected by the package data. A remote unauthenticated attacker may be able to compromise confidentiality, integrity, and availability where a vulnerable service is reachable over the network.

mitigation

Upgrade JP1/Automatic Job Management System 3 Manager, Agent, and Agent Minimal Edition to version 13-50-31 or later. Until upgrades are complete, restrict network access to affected services to trusted hosts.

fixed in 13-50-31
