The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to use after free error in the Routing Protocol Daemon (rpd). A remote user can cause a denial of service (DoS) attack.
On all Junos OS and Junos Evolved platforms, if a routing-instance deactivation is triggered, and at the same time a specific SNMP request is received, a segmentation fault occurs which causes rpd to crash and restart.
