Technical Description

A Use After Free vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated, network-based attacker to cause a Denial of Service (DoS).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.
