Details

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. 

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: 

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

Junos OS Evolved: 

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