Title
SRX5000 Series with SPC3, SRX4000 Series, and vSRX: When PowerMode IPsec is configured, the PFE will crash upon receipt of a malformed ESP packet
Summary
An Improper Validation of Specified Index, Position, or Offset in Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). On SRX5000 Series with SPC3, SRX4000 Series, and vSRX, when PowerMode IPsec is configured and a malformed ESP packet matching an established IPsec tunnel is received the PFE crashes. This issue affects Juniper Networks Junos OS on SRX5000 Series with SPC3, SRX4000 Series, and vSRX: All versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2.
