Detail

An Out-of-Bounds Read vulnerability in

the routing protocol daemon (rpd) of

Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, logically adjacent BGP peer 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 family traffic-engineering (BGP-LS)
configured

and can be exploited from a directly connected and configured BGP peer.Â

This issue affects iBGP and eBGP

with

any address family

configured, and both IPv4 and IPv6 are affected by this vulnerability.

This issue affects:

Junos OS:Â

* All versions before 21.4R3-S9,Â
* from 22.2 before 22.2R3-S5,Â
* from 22.3 before 22.3R3-S4,Â
* from 22.4 before 22.4R3-S5,Â
* from 23.2 before 23.2R2-S3,Â
* from 23.4 before 23.4R2-S3,Â
* from 24.2 before 24.2R1-S2, 24.2R2;Â

Junos OS Evolved:Â

* All versions before 21.4R3-S9-EVO,Â
* from 22.2 before 22.2R3-S5-EVO,Â
* from 22.3 before 22.3R3-S4-EVO,Â
* from 22.4 before 22.4R3-S5-EVO,Â
* from 23.2 before 23.2R2-S3-EVO,Â
* from 23.4 before 23.4R2-S2-EVO,Â
* from 24.2 before 24.2R1-S2-EVO, 24.2R2-EVO.

This is a similar, but different vulnerability than the issue reported as CVE-2024-39516.
