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.
