An Improper Handling of Inconsistent Special Elements vulnerability in the Junos Services Framework (jsf) module of Juniper Networks Junos OS allows an unauthenticated network based attacker to cause a crash in the Packet Forwarding Engine (pfe) and thereby resulting in a Denial of Service (DoS).
Upon receiving malformed SSL traffic, the PFE crashes. A manual restart will be needed to recover the device.
This issue only affects devices with Juniper Networks Advanced Threat Prevention (ATP) Cloud enabled with Encrypted Traffic Insights (configured via ‘security-metadata-streaming policy’).
This issue affects Juniper Networks Junos OS:
* All versions prior to 20.4R3-S8, 20.4R3-S9;
* 21.1 version 21.1R1 and later versions;
