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.

* 21.4 versions before 21.4R3-S5,
* 22.2 versions before 22.2R3-S3,
* 22.3 versions before 22.3R3-S2,
* 22.4 versions before 22.4R3,
* 23.2 versions before 23.2R2.
