Name of the Vulnerable Software and Affected Versions Junos OS versions prior to 21.3R3-S1 Junos OS versions 21.4 prior to 21.4R3 Junos OS versions 22.1 prior to 22.1R2 Junos OS versions 22.2 prior to 22.2R1-S2, 22.2R2

Description A deadlock in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series can be exploited by an unauthenticated, network-based attacker to cause a Denial of Service (DoS). This occurs when a large amount of traffic is processed by ATP Cloud inspection, potentially resulting in a PFE crash and restart. The crash is dependent on system internal timing, which is outside the attacker's control.

Recommendations For versions prior to 21.3R3-S1, update to version 21.3R3-S1 or later. For versions 21.4 prior to 21.4R3, update to version 21.4R3 or later. For versions 22.1 prior to 22.1R2, update to version 22.1R2 or later. For versions 22.2 prior to 22.2R1-S2, 22.2R2, update to version 22.2R1-S2, 22.2R2 or later.
