In a Dynamic Host Configuration Protocol version 6 (DHCPv6) environment, the jdhcpd daemon may crash and restart upon receipt of certain DHCPv6 solicit messages received from a DHCPv6 client. By continuously sending the same crafted packet, an attacker can repeatedly crash the jdhcpd process causing a sustained Denial of Service (DoS) to both IPv4 and IPv6 clients. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D171, 15.1X49-D180; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496; 16.1 versions prior to 16.1R3-S10, 16.1R7-S4; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S2; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R1-S2.

If REST API is enabled, the Junos OS login credentials are vulnerable to brute force attacks. The high default connection limit of the REST API may allow an attacker to brute-force passwords using advanced scripting techniques. Additionally, administrators who do not enforce a strong password policy can increase the likelihood of success from brute force attacks. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D160; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D495, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S3; 16.1X65 versions prior to 16.1X65-D49; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S2; 17.4 versions prior to 17.4R1-S6, 17.4R2-S2; 18.1 versions prior to 18.1R2-S4, 18.1R3-S1; 18.2 versions prior to 18.2R1-S5; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R1-S1.

On Junos OS, rpcbind should only be listening to port 111 on the internal routing instance (IRI). External packets destined to port 111 should be dropped. Due to an information leak vulnerability, responses were being generated from the source address of the management interface (e.g. fxp0) thus disclosing internal addressing and existence of the management interface itself. A high rate of crafted packets destined to port 111 may also lead to a partial Denial of Service (DoS). Note: Systems with fxp0 disabled or unconfigured are not vulnerable to this issue. This issue only affects Junos OS releases based on FreeBSD 10 or higher (typically Junos OS 15.1+). Administrators can confirm whether systems are running a version of Junos OS based on FreeBSD 10 or higher by typing: user@junos> show version | match kernel JUNOS OS Kernel 64-bit [20181214.223829_fbsd-builder_stable_10] Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X53 versions prior to 15.1X53-D236; 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8; 17.3 versions prior to 17.3R2; 17.4 versions prior to 17.4R1-S1, 17.4R1-S7, 17.4R2.

The Junos OS kernel crashes after processing a specific incoming packet to the out of band management interface (such as fxp0, me0, em0, vme0) destined for another address. By continuously sending this type of packet, an attacker can repeatedly crash the kernel causing a sustained Denial of Service. Affected releases are Juniper Networks Junos OS: 17.2 versions prior to 17.2R1-S7, 17.2R3; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S4, 17.4R2; 17.2X75 versions prior to 17.2X75-D110; 18.1 versions prior to 18.1R2.

A Denial of Service (DoS) vulnerability in BGP in Juniper Networks Junos OS configured as a VPLS PE allows an attacker to craft a specific BGP message to cause the routing protocol daemon (rpd) process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition. This issue only affects PE routers configured with BGP Auto discovery for LDP VPLS. Other BGP configurations are unaffected by this vulnerability. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D81; 12.3 versions prior to 12.3R12-S12; 12.3X48 versions prior to 12.3X48-D76; 14.1X53 versions prior to 14.1X53-D48; 15.1 versions prior to 15.1F6-S12, 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D150; 15.1X53 versions prior to 15.1X53-D235, 15.1X53-D495, 15.1X53-D590, 15.1X53-D68; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S1; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3; 17.3 versions prior to 17.3R2-S4, 17.3R3; 17.4 versions prior to 17.4R1-S5, 17.4R2; 18.1 versions prior to 18.1R2-S3, 18.1R3.

Receipt of a malformed packet on MX Series devices with dynamic vlan configuration can trigger an uncontrolled recursion loop in the Broadband Edge subscriber management daemon (bbe-smgd), and lead to high CPU usage and a crash of the bbe-smgd service.
