The Juniper Networks NetScreen Firewall devices with ScreenOS before 6.3r17, when configured to use the internal DNS lookup client, allows remote attackers to cause a denial of service (crash and reboot) via a sequence of malformed packets to the device IP.

Security readout for executives and security teams

This flaw can let a remote attacker crash and reboot certain Juniper NetScreen firewalls. The business risk is service interruption at a network control point, not data theft based on the supplied sources. Exposure depends on older ScreenOS versions and use of the internal DNS lookup client. Likely exposure is limited to legacy Juniper NetScreen Firewall deployments running ScreenOS before 6.3r17 with the internal DNS lookup client enabled and reachable device IPs. Treat as a targeted availability risk for legacy perimeter infrastructure. Prioritize if affected firewalls protect critical services or have reachable device IPs. If no legacy NetScreen devices remain, business urgency is low. Mitigation focus: Upgrade affected ScreenOS deployments to 6.3r17 or later.; Review Juniper JSA10632 for official remediation details.; Restrict management and device IP exposure where operationally possible..
