Juniper Junos 12.1X44 before 12.1X44-D45, 12.1X46 before 12.1X46-D25, 12.1X47 before 12.1X47-D15, 12.3 before 12.3R9, 13.1 before 13.1R4-S3, 13.2 before 13.2R6, 13.3 before 13.3R5, 14.1 before 14.1R3, and 14.2 before 14.2R1 does not properly handle double quotes in authorization attributes in the TACACS+ configuration, which allows local users to bypass the security policy and execute commands via unspecified vectors.

The Juniper MX Series routers with Junos 13.3R3 through 13.3Rx before 13.3R6, 14.1 before 14.1R4, 14.1X50 before 14.1X50-D70, and 14.2 before 14.2R2, when configured as a broadband edge (BBE) router, allows remote attackers to cause a denial of service (jpppd crash and restart) by sending a crafted PAP Authenticate-Request after the PPPoE Discovery and LCP phase are complete.

Juniper Junos 11.4 before R12, 12.1 before R10, 12.1X44 before D35, 12.1X45 before D25, 12.1X46 before D20, 12.1X47 before D10, 12.2 before R8, 12.2X50 before D70, 12.3 before R6, 13.1 before R4-S3, 13.1X49 before D55, 13.1X50 before D30, 13.2 before R4, 13.2X50 before D20, 13.2X51 before D26 and D30, 13.2X52 before D15, 13.3 before R2, and 14.1 before R1, when a RADIUS accounting server is configured as [system accounting destination radius], creates an entry in /var/etc/pam_radius.conf, which might allow remote attackers to bypass authentication via unspecified vectors.

Juniper Junos 11.4 before R12-S4, 12.1X44 before D35, 12.1X45 before D30, 12.1X46 before D25, 12.1X47 before D10, 12.2 before R9, 12.2X50 before D70, 12.3 before R7, 13.1 before R4 before S3, 13.1X49 before D55, 13.1X50 before D30, 13.2 before R5, 13.2X50 before D20, 13.2X51 before D26 and D30, 13.2X52 before D15, 13.3 before R3, and 14.1 before R1 allows remote attackers to cause a denial of service (router protocol daemon crash) via a crafted RSVP PATH message.

Juniper Junos OS 9.1 through 11.4 before 11.4R11, 12.1 before R10, 12.1X44 before D40, 12.1X46 before D30, 12.1X47 before D11 and 12.147-D15, 12.1X48 before D41 and D62, 12.2 before R8, 12.2X50 before D70, 12.3 before R6, 13.1 before R4-S2, 13.1X49 before D49, 13.1X50 before 30, 13.2 before R4, 13.2X50 before D20, 13.2X51 before D25, 13.2X52 before D15, 13.3 before R2, and 14.1 before R1, when supporting 4-byte AS numbers and a BGP peer does not, allows remote attackers to cause a denial of service (memory corruption and RDP routing process crash and restart) via crafted transitive attributes in a BGP UPDATE.

Juniper Junos 11.4 before 11.4R12, 12.1 before 12.1R10, 12.1X44 before 12.1X44-D35, 12.1X45 before 12.1X45-D25, 12.1X46 before 12.1X46-D20, 12.1X47 before 12.1X47-D10, 12.2 before 12.2R8, 12.3 before 12.3R7, 13.1 before 13.1R4, 13.2 before 13.2R4, 13.3 before 13.3R2, and 14.1 before 14.1R1, when Auto-RP is enabled, allows remote attackers to cause a denial of service (RDP routing process crash and restart) via a malformed PIM packet.

Juniper Junos 11.4 before 11.4R12, 12.1 before 12.1R11, 12.1X44 before 12.1X44-D35, 12.1X45 before 12.1X45-D30, 12.1X46 before 12.1X46-D20, 12.1X47 before 12.1X47-D10, 12.2 before 12.2R8-S2, 12.3 before 12.3R7, 13.1 before 13.1R4-S2, 13.2 before 13.2R5, 13.3 before 13.3R2-S2, and 14.1 before 14.1R1 allows remote authenticated users to gain privileges via unspecified combinations of CLI commands and arguments.

Memory leak in Juniper JUNOS Packet Forwarding Engine (PFE) allows remote attackers to cause a denial of service (memory exhaustion and device reboot) via certain IPv6 packets.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.
