CVE-2024-39528: Junos OS and Junos OS Evolved: Concurrent deletion of a routing-instance and receipt of an SNMP request cause an RPD crash

First published: Thu Jul 11 2024(Updated: )

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. This issue affects:    Junos OS: * All versions before 21.2R3-S8,  * 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.   Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4-EVO versions before 21.4R3-S5-EVO, * 22.2-EVO versions before 22.2R3-S3-EVO,  * 22.3-EVO versions before 22.3R3-S2-EVO, * 22.4-EVO versions before 22.4R3-EVO, * 23.2-EVO versions before 23.2R2-EVO.
