Description

An Out-of-Bounds Read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects systems configured in either of two ways: *systems with BGP traceoptions enabled *systems with BGP traffic engineering configured This issue can affect iBGP and eBGP with any address family configured. The specific attribute involved is non-transitive, and will not propagate across a network. This issue affects: Junos OS:  *All versions before 21.4R3-S8, *22.2 before 22.2R3-S5,  *22.3 before 22.3R3-S4,  *22.4 before 22.4R3-S3,  *23.2 before 23.2R2-S2,  *23.4 before 23.4R2;  Junos OS Evolved:  *All versions before 21.4R3-S8-EVO,  *22.2-EVO before 22.2R3-S5-EVO,  *22.3-EVO before 22.3R3-S4-EVO,  *22.4-EVO before 22.4R3-S3-EVO,  *23.2-EVO before 23.2R2-S2-EVO,  *23.4-EVO before 23.4R2-EVO.
