Name of the Vulnerable Software and Affected Versions: Junos OS versions prior to 21.2R3-S9 Junos OS versions from 21.4 before 21.4R3-S10 Junos OS versions from 22.2 before 22.2R3-S6 Junos OS versions from 22.4 before 22.4R3-S4 Junos OS versions from 23.2 before 23.2R2-S2 Junos OS versions from 23.4 before 23.4R2 Junos OS Evolved versions prior to 21.2R3-S9-EVO Junos OS Evolved versions from 21.4-EVO before 21.4R3-S10-EVO Junos OS Evolved versions from 22.2-EVO before 22.2R3-S6-EVO Junos OS Evolved versions from 22.4-EVO before 22.4R3-S4-EVO Junos OS Evolved versions from 23.2-EVO before 23.2R2-S2-EVO Junos OS Evolved versions from 23.4-EVO before 23.4R2-EVO

Description: A Buffer Access with Incorrect Length Value issue 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). This occurs when an attacker sends a specific ICMPv6 packet to an interface with "protocols router-advertisement" configured, causing rpd to crash and restart. Continued receipt of this packet will cause a sustained DoS condition. This issue only affects systems configured with IPv6.

Recommendations: For Junos OS versions prior to 21.2R3-S9, update to version 21.2R3-S9 or later. For Junos OS versions from 21.4 before 21.4R3-S10, update to version 21.4R3-S10 or later. For Junos OS versions from 22.2 before 22.2R3-S6, update to version 22.2R3-S6 or later. For Junos OS versions from 22.4 before 22.4R3-S4, update to version 22.4R3-S4 or later. For Junos OS versions from 23.2 before 23.2R2-S2, update to version 23.2R2-S2 or later. For Junos OS versions from 23.4 before 23.4R2, update to version 23.4R2 or later. For Junos OS Evolved versions prior to 21.2R3-S9-EVO, update to version 21.2R3-S9-EVO or later. For Junos OS Evolved versions from 21.4-EVO before 21.4R3-S10-EVO, update to version 21.4R3-S10-EVO or later. For Junos OS Evolved versions from 22.2-EVO before 22.2R3-S6-EVO, update to version 22.2R3-S6-EVO or later. For Junos OS Evolved versions from 22.4-EVO before 22.4R3-S4-EVO, update to version 22.4R3-S4-EVO or later. For Junos OS Evolved versions from 23.2-EVO before 23.2R2-S2-EVO, update to version 23.2R2-S2-EVO or later.
