The stateless firewall in Juniper Junos 13.3R3, 14.1R1, and 14.1R2, when using Trio-based PFE modules, does not properly match ports, which might allow remote attackers to bypass firewall rule.
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.
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.
