Summary

In MPLS environments, receipt of a specific SNMP packet may cause the routing protocol daemon (RPD) process to crash and restart. By continuously sending a specially crafted SNMP packet, an attacker can repetitively crash the RPD process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS : 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior to 12.3X48-D75 on SRX Series; 14.1X53 versions prior to 14.1X53-D48 on EX/QFX series; 15.1 versions prior to 15.1R4-S9, 15.1R7-S2; 15.1F6 versions prior to 15.1F6-S11; 15.1X49 versions prior to 15.1X49-D141, 15.1X49-D144, 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D234 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D471, 15.1X53-D490 on NFX Series; 15.1X53 versions prior to 15.1X53-D590 on EX2300/EX3400 Series; 15.1X54 on ACX Series; 16.1 versions prior to 16.1R3-S10, 16.1R4-S11, 16.1R6-S5, 16.1R7; 16.1X65 versions prior to 16.1X65-D48; 16.2 versions prior to 16.2R2-S6; 17.1 versions prior to 17.1R2-S8, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D92, 17.2X75-D102, 17.2X75-D110; 17.3 versions prior to 17.3R3; 17.4 versions prior to 17.4R1-S4, 17.4R2; 18.1 versions prior to 18.1R1-S1, 18.1R2-S1, 18.1R3; 18.2X75 versions prior to 18.2X75-D10.
