A Double Free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS).
In a remote access VPN scenario, if a "tcp-encap-profile" is configured and a sequence of specific packets is received, a flowd crash and restart will be observed.
This issue affects Juniper Networks Junos OS on SRX Series:
* All versions earlier than 20.4R3-S8;
* 21.2 versions earlier than 21.2R3-S6;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S5;
* 22.1 versions earlier than 22.1R3-S3;
* 22.2 versions earlier than 22.2R3-S3;
