description: An error handling vulnerability in Routing Protocols Daemon (RPD) of Juniper Networks Junos OS allows an attacker to cause RPD to crash. Continued receipt of this malformed MPLS RSVP packet will cause a sustained Denial of Service condition. Affected releases are Juniper Networks Junos OS: 14.1 versions prior to 14.1R8-S5, 14.1R9; 14.1X53 versions prior to 14.1X53-D48 on QFX Switching; 14.2 versions prior to 14.1X53-D130 on QFabric System; 14.2 versions prior to 14.2R4. This issue does not affect versions of Junos OS before 14.1R1. Junos OS RSVP only supports IPv4. IPv6 is not affected by this issue. This issue require it to be received on an interface configured to receive this type of traffic.
