Description

An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart. This issue affects: Junos OS: *22.4 versions before 22.4R3-S1, *23.2 versions before 23.2R2,  *23.4 versions before 23.4R1-S1, 23.4R2,  This issue does not affect Junos OS versions earlier than 22.4R1. Junos OS Evolved: *22.4-EVO versions before 22.4R3-S2-EVO, *23.2-EVO versions before 23.2R2-EVO, *23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO, This issue does not affect Junos OS Evolved versions earlier than before 22.4R1.
