A Buffer Access with Incorrect Length Value vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When an attacker sends a specific ICMPv6 packet to an interface with "protocols router-advertisement" configured, rpd crashes and restarts. Continued receipt of this packet will cause a sustained DoS condition.
This issue only affects systems configured with IPv6.
This issue affects Junos OS:
* All versions before 21.2R3-S9,
* from 21.4 before 21.4R3-S10,
* from 22.2 before 22.2R3-S6,
* from 22.4 before 22.4R3-S4,
* from 23.2 before 23.2R2-S2,
* from 23.4 before 23.4R2;
and Junos OS Evolved:
* All versions before 21.2R3-S9-EVO,
* from 21.4-EVO before 21.4R3-S10-EVO,
* from 22.2-EVO before 22.2R3-S6-EVO,
* from 22.4-EVO before 22.4R3-S4-EVO,
