Description

Receipt of a specific Draft-Rosen MVPN control packet may cause the routing protocol daemon (RPD) process to crash and restart or may lead to remote code execution. By continuously sending the same specific Draft-Rosen MVPN control packet, an attacker can repeatedly crash the RPD process causing a prolonged denial of service. This issue may occur when the Junos OS device is configured for Draft-Rosen multicast virtual private network (MVPN). The VPN is multicast-enabled and configured to use Protocol Independent Multicast (PIM) protocol within the VPN. This issue can only be exploited from the PE device within the MPLS domain which is capable of forwarding IP multicast traffic in core. End-users connected to the CE device cannot cause this crash. 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-D70 on SRX Series; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1F6; 15.1X49 versions prior to 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D59 on EX2300/EX3400 Series; 15.1X53 versions prior to 15.1X53-D67 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D471, 15.1X53-D490 on NFX Series; 16.1 versions prior to 16.1R4-S9, 16.1R5-S4, 16.1R6-S3, 16.1R7; 16.2 versions prior to 16.2R1-S6, 16.2R2-S6, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R2-S4, 17.2R3; 17.3 versions prior to 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S3, 17.4R2; 18.1 versions prior to 18.1R2.
