\n\nThis issue only affects systems configured in\n either of two ways:
\n \n
    \n
  1. systems with BGP traceoptions enabled
    2. \n
  2. systems with BGP family traffic-engineering (BGP-LS)\n configured
\n\n and can be exploited from a directly connected and configured BGP peer. 

This issue affects iBGP and eBGP \n\nwith \n\nany address family\n\n configured, and both IPv4 and IPv6 are affected by this vulnerability.

This issue affects:

Junos OS: 

  • \n\nfrom 21.4 before 21.4R3-S9, 
  • from 22.2 before 22.2R3-S5, 
  • from 22.3 before 22.3R3-S4,

  • from 23.4 before 23.4R2-S3, 
  • from 24.2 before 24.2R1-S2, 24.2R2; 

Junos OS Evolved: 

  • from 21.4-EVO before 21.4R3-S9-EVO, 
  • from 22.2-EVO before 22.2R3-S5-EVO, 
  • from 22.3-EVO before 22.3R3-S4-EVO, 
  • from 22.4-EVO before 22.4R3-S5-EVO,

  • from 24.2-EVO before 24.2R1-S2-EVO, 24.2R2-EVO.
This issue does not affect versions of Junos OS prior to 21.3R1.
\n\nThis issue does not affect versions of Junos OS Evolved prior to 21.3R1-EVO.\n\n

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