Description

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).<br /> 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. <br /> <br /> <br /> <br /> <br /> This issue only affects systems configured with IPv6.<br /> <br /> <br /> <br /> This issue affects Junos OS: <br /> <br /> <br /> * All versions before 21.2R3-S9, <br /> * from 21.4 before 21.4R3-S10, <br /> * from 22.2 before 22.2R3-S6, <br /> * from 22.4 before 22.4R3-S4, <br /> * from 23.2 before 23.2R2-S2, <br /> * from 23.4 before 23.4R2; <br /> <br /> <br /> <br /> and Junos OS Evolved: <br /> * All versions before 21.2R3-S9-EVO, <br /> * from 21.4-EVO before 21.4R3-S10-EVO, <br /> * from 22.2-EVO before 22.2R3-S6-EVO, <br /> * from 22.4-EVO before 22.4R3-S4-EVO, <br /> * from 23.2-EVO before 23.2R2-S2-EVO, <br /> * from 23.4-EVO before 23.4R2-EVO.
