Repeated exploitation of this vulnerability causes a complete inability to establish new VPN connections.\n\nThis issue affects Junos OS on \n\nSRX Series and MX Series:\n\n\n\n  *  all versions before 22.4R3-S9,\n  *  23.2 version before 23.2R2-S6,\n  *  23.4 version before 23.4R2-S7,\n  *  24.2 versions before 24.2R2-S4,\n  *  24.4 versions before 24.4R2-S3,\n  *  25.2 versions before 25.2R1-S2, 25.2R2.",
