EUVD |
EUVD-2019-0873 | An unexpected status return value weakness in the Next-Generation Multicast VPN (NG-mVPN) service of Juniper Networks Junos OS allows attacker to cause a Denial of Service (DoS) condition and core the routing protocol daemon (rpd) process when a specific malformed IPv4 packet is received by the device running BGP. This malformed packet can be crafted and sent to a victim device including when forwarded directly through a device receiving such a malformed packet, but not if the malformed packet is first de-encapsulated from an encapsulated format by a receiving device. Continued receipt of the malformed packet will result in a sustained Denial of Service condition. This issue affects: Juniper Networks Junos OS 15.1 versions prior to 15.1F6-S12, 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D68, 15.1X53-D235, 15.1X53-D495, 15.1X53-D590; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S2; 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. |
